Goodbye Fun Fun Function (and the importance of mental health) 

I was homeless for nearly a year due to crappy circumstances, and I literally used to watch your videos in a Denny's booth wifi all night to learn modern tech stacks. Ended up getting a job at a software company remotely, and was able to get a long-term motel room and then a house. Crazy to think about. I really appreciate all you've done to teach technology graciously, and freely. I'm gonna miss you, man!

Three years ago already. I miss this show. I hope you feel better.

You taught me Promises, I'll never forget that.

"If you're confused, you're learning." That was one of the most helpful things I've ever heard. Thank you for what you've done Mattias. You've helped me get a developer job and I'll always be grateful to you.

Dear MPJ, sending lots of love (and rainbows and all that) from Brooklyn, NY. Congratulations on this new adventure! Your work on Fun Fun Function is one of my inspirations and I cherish the times we have gotten to collaborate. Whenever you have the itch again, you are always welcome to board the Coding Train and say hello to your many fans! Looking forward to staying in touch! I hope to stop by the goodbye stream!

I rarely comment on youtube videos, but I just have to say this: You kept me hungry, and you helped me keep my job in so many ways you can't imagine. Just like me, there's thousand on who you also had such a huge impact. You'll be missed mister, take care

Learned javascript because of your channel and have the courage to share it in my channel because of you.. thank you so much Mattias, You'll be missed

You are an inspiring human being MPJ, wish you best of success. Thanks for everything

Mattias, I'm both SO excited for your new chapter and feel really sad that you're closing this chapter of your life (for now). You were one of the very first tech youtubers I talked to when I first started, and I seriously loved all of our deep conversations about life, tech, youtubing, and mental health. Getting to meet you and Isa in Sweden last summer was absolutely a highlight of my year, and Scott and I reminisce often about that night. I love that you're following a passion of yours and found a great intersection between code and mental health -- I can't help but think this has been brewing and in the works for many months! I know you're going to love working as a developer again, and that the impact you make there will be immeasurable and profound too.Thank you so much for creating and leading this incredible community on RU-vid; you've been such an incredible role model to me and will continue to be so 💖Sending so much love and energy to you and Isa as you step into the next chapter of your life.

Dude, your'e one of the reasons i am working as a developer for almost two years now, your'e a LEGEND, never forget that!

Still waiting for the return of MPJ. I feel like RU-vid needs you more than ever, especially after what the world has become.

I'm just sad that I discovered this amazing channel after its end. I would've loved to have joined the community

I'M NOT CRYING, YOU'RE CRYING

I totally understand mental health. I struggled with suicide in my early teens. And was in the mental health system for several years. Funny that my desire to be a developer is what ended up making me want to get better. I spent all of my time in mental hospitals reading programming books, and writing code on paper. This was at a time when they would often give your thorazine. This was way back in the late 90s, early 2000s. My ability to be a good programmer is what helped me rise above my circumstances. As I get older, and social media exposes more people. I find that people I wouldn't even expect, are suffering mental issues. I use to be ashamed of my past, but now I think it's my greatest strength. From being institutionalized for 2 years, to a near 20 year career as a developer. Don't underestimate the power of your message and platform here.

Sometimes I come back to this video and just reflect on all the impact you've had in my life. Miss you

What an impact this channel has had on the world ❤️❤️❤️ You'll be missed on YT; best of luck moving forward!

When I was 22 I lost my last parent which was my mother and now that I'm 25, after struggling with depression for over 10 years, it is very important that you leave any toxic environment you are in. Whether it is your job, your household or any other relationship. If it does bad things to you, drop out. I have been so often attempting to end it all that I've came to that conclusion.

You’re a legend for damn sure! You’ve helped me not only with JS, but inspiration for my channel and streaming. Good luck in your journey brother!

It took a lot of courage to do this, to be a knowledge bearer, and it took balls of steel to share your story, what happened to your mom. You helped me learn HOFs and functional programming, and I'm certainly appreciative. But it's your personality and your grace that make you truly unique. You have helped so many, and even as you close the door on fun fun functions, you inspire each of us to follow our paths with dedication and conviction...and gratitude...and fun. I'll be following you, Mathias. Thanks a million for fff, and I can't wait to see what's next. XO!

You were one of the first educators I discovered when I decided to become a developer. You've been hugely motivating and inspiring. Good luck in all you do!

Holding my tears here, friend. Take care, we love you, and "stay curious".

I found myself crying by the latter half of this. You will be sorely missed. Fun Fun Function has been a huge blessing for my curiosity and my career. The world is rooting for you, always.

Sometimes I click on this channel just to see if you're back. Hope you're doing well mate.

"Stay curious" was the best way to finish the video that puts a break into the channel. I wish you luck and success on the new journey you are starting. Thanks MPJ!

It was so good to see "tech" human being so emotionally open, not shying away from hard topics. Thank you and good luck :)

Throughout my programming journey, you are one of the most coolest devs I know and I have learned so much from you. I may be a lurker on the community but I really had fun watching your videos. I'm really thankful that you created this channel as a medium to share your knowledge and help aspiring developers like me. You always give me motivation to succeed in my dreams of being a developer. You taught me to always "stay curious" and I really thank you for that. Good luck on your next journey mpj! Can't wait to see the projects around mental health that you'll build with Mindler. Love from the Philippines ❤️

I came to your channel looking to learn JS generators. Your channel has been my go to recently. Your style of narration, the doodle on your notebook are all just absolutely awesome. Please know that you have touched so many lives, helping us build our career. You are a wonderful person. I wish you the best in life!

Hey, MPJ! I just now saw this on my feed when I opened RU-vid, so I didn't get to attend the Goodbye Live Stream event, and I'm sad I missed it... But! I just wanted to tell you that YOUR videos helped me execute a career reboot: I shut down my "working stiff at a dead-end job" self, and installed a fresh new "passionate IT professional" operating system. Now I'm working with big data and solving interesting problems for a living, and it's all because of content creators and virtual mentors like YOU, who helped me pick up tech skills in my spare time. YOUR videos in particular were essential study material while I was working on my Front-End Web Developer Nanodegree at Udacity. I am a new man today, barely recognizable from my 5-years-ago self, and YOU played a central part in that transformation. Thank you for everything you've done, for me and for this community. I hope this change of pace helps you heal, and gives you the time and perspective necessary to decide on your next move. Much love and gratitude, from Iowa, USA, James

I have taught hundreds of students to be full stack Javascript Engineers at a leading US Bootcamp and can't tell you how much you have helped our community of ambitious but nervous career-changers. You have helped them see that this work can be fun and accessible. You helped them navigate challenging new concepts. Both helped make their journeys easier. I used to give links to your videos to students as they struggled with specific concepts from time-to-time as a complement to what we did. Sometimes the enthusiasm and joy of your videos gave them a needed respite from the rigors and challenges of our program (all while moving their skills forward). When I started noticing they were discovering you and passing around your videos amongst themselves, I danced a little jig. They were learning to use the web to advance their own knowledge and they found you as helpful and empowering as I had hoped. Thank you for your years of contribution to our community. We will miss you.

Oh, 2020, just couldn't get better!🤦‍♂️ Just so you know, you're not just in our screens, you're in our hearts MPJ 💛❤️💛 Wish you best of luck ... and until some Monday, we'll stay curious 🙂

I was directed to your videos in university a long time ago, well a few years back. I think your channel was new then. I didn't keep up with university because I was also working full time at the time and it eventually became too much. Today, pretty much a month ago now marks my first year working a new job as a developer and I still refer back to your videos when I need a refresher on a concept! Right now I'm learning about unit testing from you because the projects I'm working on have become so large I can't keep them in my head anymore. Thank you for creating this archive of knowledge.

I started watching your videos over the years. At first yeah... promises, ES5/6, UNIT TEST... but then it was learning how to feel valuable in what I do and appreciate the people I work with or where I work or what I'm doing with my time. Taking breaks. Taking walks. You've always talked a lot on mental health and tackling it. This is a great opportunity for you. Thank you MPJ. For everything. I wish I hadn't missed the live stream!

It has been a privilege to have a teacher, mentor, someone with an insight like you. You make the audience completely forget about the unhealthy robotic competitive mindset and just discover the child like curiosity and grow with it. It wasn’t just development you taught and i am grateful for it

Interesting timing. I just opened RU-vid, thinking "I'm gonna watch some FFF" and this video JUST dropped. I will miss FFF very much, but I am very happy for you. Having been through some things myself, I believe mental health is VERY important, but often very neglected as well. It's great that a mental health startup will have the power of MPJ on their team. Best of luck to you, and thank you so much for Fun Fun Function.

My 15 year old sister was diagnosed with anorexia exactly a year ago. Her weight dropped so low she started having problems with her heart and other organs. She has been in and out of a hospital for months, but the hardest part of the disorder is her not realizing she is ill. It has affected our whole family, and it's difficult as we can't do much else than wait and pray for her. Mental health is not like any other physical injury. It can't be treated from the outside, and these wounds heal painfully slowly. They require an enormous amount of understanding from others and strength from the patient. Always make sure the people around you know they have you to rely on when it gets hard.

Good luck MPJ!

I have grown as a developer during the life cycle of this channel, really appreciate the work and content you have provided to the whole community. love from India.

Thank you for this journey, I started loving FP thanks to you and I started a RU-vid channel inspired on what you did so far. We will miss you and for many you are a reference to the world. Until the next one, good journey Matias. This is just the beginning.

I discovered your channel when I was working abroad as a chambermaid in a shitty luxurious hotel for the winter season. I remember watching your videos in my small room and learning from them when I wasn't at work & thinking of those videos and my small JS projects on my shift while cleaning the rooms. Thank you so much for being there for me, man! :)

community missing you, Thanks for your effort

Dude, you made me cry! I’ll never forget your “composition over inheritance” video, it is definitely in my favourite pool 😄 thanks and all the best!

Take care 👍And congrats on working with Mindler this is a beautiful project! It is important to care about mental health.

This literally had me in tears. 😭 You taught me so much!!! I will miss you. :(

I just found your videos yesterday and already consumed 10+ hours of your content, so now coming across this video is somewhat bittersweet. I’m so thankful for these videos that you’ve made, but over everything you need to take care of yourself and think about your own passions and wants. The fact I’m sitting here teary-eyed after only ‘knowing you’ for a little over 24 hours, whilst watching this video is a huge testament to you as a person. Have a fantastic life, my friend.

Take care MPJ, you've been a massive inspiration for me as a software engineer. Thanks for helping me grow and stay curious.

It is my deepest wish that the kind person we have come to know through FFF continues to grow and thrive more, outpacing any negative feelings or demons you may have, by exponential amounts no matter which direction in life you take. We love you, sibling programmer.

You taught me Higher Order Functions and so many amazing Javascript concepts that helped me scoring my first ever job as a developer 3 years back. Can't thank you enough really. Much love to you!

Really, really, really, really, really, really, really, really it has been a great pleasure to learn my way to be a better engineer watching these videos during so many years. I greatly appreciate all the love and effort you have put in this educational series. As a self made engineer, not from CS traditional school, this have been one of my fave courses here at my invisible college for no degree. Thanks, Gracias, Eskarrik Asko, Tack!

I teach frontend development professionally and I don't know how many students I've sent your way. You will be missed. But your videos are still with us, and we're proud of you and your decision to focus - not only on the simple joy of JUST coding - but on helping humanity find ways to talk through our problems and our relationships. Mental health is such an incredibly central and pressing need. Good health! I hope to see you on Monday morning. Either way, stay curious and thank you so, so much.

You're what the internet has always been about, spreading knowledge to make a better world. The impact you've had in people's life is way bigger than you probably imagine, your videos will be very missed. Stay curious, looking forward to hear from you again!

Thank you so much, Mattias. There is no other person in the world who made such a remarkable impact on my journey as a software developer and career as you. Thank you for bringing fun and curiosity in my life alongside some wisdom and inspiration. I already miss that GoodMondayMornings that made my days and helped me to get through all challenges that I had. I hope I have a chance to meet you in person one day and say "thank you" one more time. I wish you all the best in your life and looking forward to seeing you online again.

I haven’t developed professionally in over 13 years, but I learned a tremendous amount from your content. I’m now responsible for leading an organization that has many talented developers and I’ve used your videos to help me better understand what is important to development teams and even get some skills myself to help work though challenges (without laying code of course). I’ve shared your content with our tech leaders through the years and I suspect they themselves continued learning from you. Best of luck and thank you generously sharing your insights on practices and attaining satisfaction in one’s efforts. Jason San Antonio, TX

This got me: “last good Monday morning”. Thank you Fun Fun Function, you really made programming enjoyable for me but more so with all the meta videos. All the best for the future MPJ!

I still remember, when I was preparing for interviews for a job. I would always search for something on RU-vid regarding javascript and you were there on the top results. I remember picking up your videos, as they were "fun". Thankyou so much, for everything 🙂

I started to watch you a couple of years ago. Thank you for all the great videos and wish you nothing but health and happiness!

Your intro to functional programming videos helped me an enormous amount when I got serious about learning React in November. It completed changed my coding style for the better. Thank you for the help: it is truly appreciated!

Take care and thanks for everything! Changing is always difficult but you need to do what's best for you :)

Thank you mpj. You helped me develop my confidence as a programmer and have so much to be proud of. I absolutely respect and support your decision. We live to create.

I learnt about your show from my colleague in 2016 and have been watching since. Sad it’s coming to a stop and wish you all the best in your new journey with Mindler. Thank you 🙏

You taught me how to understand JavaScript, I can't find the words to describe my gratitude. Because of you guidance I was able to learn more things by myself and over less than 2 years, double my salary... Buy a house ... You should know that your commitment have improved life of many. To see FFF stop is sad, but what a great cause you've choose to take on. I hope you meet success in your new job, and that you stay the way you are... To me you are a teacher, and I'll never forget what you did for me...

Thank you from the bottom of my heart for everything you have ever taught me. Literally everything starting from js -> I have begun to learn from you. I appreciate the worth you have given to our community more than my meagre words can convey. I hope you take this on to your more than worthy cause. Chapeau x

"Every new beginning comes from some other beginning's end' - semisonic "also, don't say goodbye, say goodnight" - binocular see you around sensei! - me

I really apreciate all the efort you had put on the previous videos, I learnt javascript with you back in 2017 to 2019 , hope you are doing well and thank you for all ! :D

Best of luck and thanks for all the help over the years. You have been a big help in my career. Although it's sad that you are leaving, I'm really pleased you're making a change to better your life and the lives of others around you.

I've been watching for 4 years, and you've helped me more than any other source. Mental health is indeed extremely important, hopefully this will help people struggling help themselves also. I'm one of those people and may soon finally start talking. Thank you for everything and all the best to you. We'll be here if and when you come back. Stay safe and enjoy your new journey ❤️

I love this video. I’m really happy that people are spreading more and more often the message that mental health is really important and this it must be destigmatized. I also really love how passionately you talk about it. And one other thing that I love is hearing you say that this really makes you happy (and it seems that you actually mean it). Best of luck in this new job and thanks a ton for all your videos!!!

Holding my tears here. As usual, food for thought! Thank you for sharing awestruck inspiring insights, habits, and knowledge. All the best on your new journey. I'm sure you're going to keep impacting a plethora of human beings besides yourself.

Thank you so much for all that you taught us. :) I am also grateful you shared your story as to how important your new adventure is and we're all here to cheer you on! I smiled at the same time as you when you said that you were "feeling really really good about joining them". I hope I can find an opportunity to make software in this practice as well as I've been learning how valuable mindfulness, support, and mental stability is after decades of ignoring it. All the best MPJ!

I was introduced to this channel by my senior while i started off my journey as a JS developer and since then i've been a fan, follower, student, disciple. The suave and the ease of learning you bring to the table is unparalleled. I've been spreading the channel all this while and will continue to do so. I will be waiting for that sabbatical to end and to hear that iconic "Good Monday Morning" once again. Untill then, we'll continue to learn and get inspired by the one and only @MPJ. Thank you for creating it. Take care, Stay blessed, lots of love and wishes from all of us, We are with you.

I'm in charge of training new employees in my company (full stack js devs) and I have a playlist I made of Fun Fun Function videos (about 10 videos) that they have to watch during the training process. Thanks for the work you did and good luck in the new journey

Your videos made me to learn JS in a better way and I still remember every Monday I was excited to watch your new video. Thank you for this channel.

Thank you for helping me understand so many things about programming and doing it with a great energy! Take care of yourself! And if you decide to come back, your loyal and greatful audience will always be here!

❤️❤️💔😭 oh gee that got me teary and feeling sad, and also so happy for you and your new adventure! What a loss, but also a change that needs to happen. Thanks for making funfunfunction and sharing yourself with us. You've helped me a lot. I'm a self taught Dev and I was so stuck, I thought I'd never get JavaScript and then I found Funfunfunction and it just clicked! Thanks for you passion and honesty and jokes. There's so much good in your videos, I'll continue watching the old ones :) Mindler sounds like a great company, we need more people like you working in mental health. I look forward to hearing more about it. You'll be greatly missed! All the best, stay curious and don't forget your towel ❤️

After 5 years following you on RU-vid, I was very saddened by your story. I hope this new project will bring you what you want. Thank you very much for your videos which helped me to progress. Take care of yourself.

I've learnt to appreciate javascript and the good practices because of this channel. Thanks for inspiring me. This has played a major role in my personal development over the past 3 years. Thank you for everything. Cheers. Take care of yourself.

I have already watched this 7 months ago but sometimes I do watch it because being someone who don't know anything about coding and finding this guy who can give you his energy even from only one video is something unbelievable, I hope you'll grow wherever you go. Stay happy man!! Wish you a good luck, and if you'll ever came back to this, I'll always there as your supporter, fan, student and many more🙂

Thank you for the years of videos. “There is a time to learn, and a time to earn.” You we’re lucky enough to teach. Praying for you

And today Brad Traversy announced he's doing something similar, although not permanently, he's "taking a vacation of RU-vid". I guess teaching programming is so exhausting because technology is changing so fast it's freaking difficult to keep pace with it and learn the new stuff in timely manner. All the best to you and I hope you'll find what you're looking for. Greetings from Prague.

I became an developer most because of the circustances in life than for a love for computing. You showed me a very kind and fun way to see my job. Thanks a lot.

Thank You so much. I have learned a lot from you and would still be watching your old videos. Thanks for devoting so much of your time and effort in doing so. Thank You

Good luck mpj with your new job... You'll be missed... ❤️

Having been interested in becoming a programmer, I found on youtube the best programmer channels and you are among one of them, I enjoyed your story and your courage to share it, so I immediately went and subscribed to your channel and I will continue watching your videos, I hope that you come back even if it is just to know that you are well, God bless your life MPJ.

Only a few people are able to put not only great content into educational videos, but also a piece of their heart. And you are definitely one of them and the best of them. I wish you good luck on your journey through life.

NPJ You made me tear up brother! Your videos were a huge help in me landing my first professional position at the age of 37 years old. I was a high school dropout and also failed at college after the military. However, I never gave up on programming and with help from your videos, FreeCodeCamp, and LaunchCode I was able to finally PROVE my skill. I still direct people to your videos and even rewatch them myself when my other client work pulls me too far away from JS client work and I need a refresher.

"Thank you" - a message from the past to your present

It's very brave of you to expose your 'inner demons' here. Keep being brave my friend, cheers from Portugal :)

This is the first Fun Fun Function video that I came across because I was referred to it by a link in a web development preparation module. Sad to learn that you have already said goodbye over 7 months ago. However, I am glad to hear that you will be contributing to a meaningful and important cause that is dear to you. Please continue being a blessing and encouragement to everyone around you. Take care and hope to learn more of your continuing work in the future.

I'm so grateful for you and your courage! With your humor and silly examples you illuminated a dark path through JavaScript for me! Thank you so much!

I'll miss you a lot :( I've put the 13th July 7AM PT in my calendar so I can bid you farewell Blessings from Chile

That is sad 😢, Waiting for your return

I found your channel after you left for about a year. However, your videos are solving some pain points of me at work, and I feel grateful to it. People, please feel free to recommend some similar channels here. Thanks

Thank you for all that you have provided, selflessly, to the world. The origins of my path as an engineer can directly be drawn to the first handful of FFF videos. It would not be without a sense of serendipity that yesterday was the first day of my dream job as CTO of a small startup. I may have not made it here without the education you provided. We will probably never meet, but I hope you know that, at minimum, you changed the life of one person in a very substantial way. Thank you.

Возвращайся, друг 😊

Who is watching in 2023?

Thanks MPJ, when I started your videos were my best allied. I'm sure that, like me, people for all around the world know you and are grateful to you. Best wishes for all your future. Thanks from Peru.

You are my GURU. Thanks a lot for all your support and your contributions in my life.

5:12 you mentioned you've lost passion for coding then what'll be your role at "Mindler" ? I thought you'll join there as software engineer.

I Just discover this channel and this is my fav vid so far, thank you for your work, your vids, your knowledge, and promise i 'll keep curious always

I have enjoyed watching your videos for a long time now. I have had times when I wasn't enjoying my job, and I'd go into the office on Monday not thrilled to be there. I'd see the youtube update saying I had a new FFF to watch, and I'd do that before anything else. "Good Monday Morning" was an awesome start for my week. At times when my motivation was suffering, I'd rewatch the episode where you're trespassing in the quarry in the rain, talking about having the same problem, and that would make me feel a bit better. You talked a lot about the human side of tech, about jobs, about user happiness, about developer happiness, and about making it meaningful, and I appreciate that a lot. A really important thing I've learned from you, and especially important as a leader of a team, is to watch out for signs of emotional struggles in my teammates, friends and colleagues. It really does happen to everyone, and having some solid support at the right times is vital. I know people who are alcoholics, some in recovery and some still suffering. I know people who have struggled with depression, anxiety, and other things. I feel that there are things I can do for the people around me, and that I have a responsibility to not ignore those things. Nothing stays the same forever, so it's natural that FFF would evolve, and natural that you would need to do more things in your career. I will still be re-watching episodes at times, and I'll still refer younger developers to episodes (because your explanations of things are far more entertaining than mine). I hope your new path is as incredible as FFF has been. You've reached a lot of people, and brought us learning and fun. You have made a difference in the world. I have no doubt that you will continue to help people wherever you go and whatever you do. You have a passion for that and it shows. Go start your new adventure! Whenever you again feel the need to record a video and share it, I'll definitely be part of your audience.

Hey mate. Thank you for all the videos over the years. I found your channel when I moved to Bangkok in 2018 and immediately broke my hip (lol). Your videos while I was isolated for the next 8 months of recovery were really awesome and something which I genuinely looked forward to! You and David always struck me as cool guys. Best wishes on the new job.
