TypeScript - The Basics 

these videos are *money*. Perfectly spoken english at a confident pace with easy-to-understand concepts is such a rarity to find--easiest sub of my life! Love the framework-agnostic videos!

For future reference: 1:43 Getting started 3:00 tsconfig.json 4:30 Third party libraries 5:09 Type annotations 6:38 Custom types 8:12 Types in functions 9:22 Arrays 10:32 Generics

Wow, you just absolute sold me on TypeScript. I come from a Java background, and this is all I ever missed in plain JavaScript!

Object oriented /functional programming in TS please.... I love this one 😍

You are such a good teacher for those who really want to be a good coder, I love your videos thank you so much for this.

Fantastic! Please do object oriented vs functional. I've been using TypeScript for years and I learned a few things... Your videos are consistently great!

I have been using Typescript for a bit but always learn something new when watching your videos. Today it was adding a key property to an interface to allow classes implementing that interface to include additional properties. Great video!

Been using it for like 3 years now. Loved your overview. Will share this with some of the junior devs on my teams. Thanks!

Lol... Finally now there is a video with most practical use cases with TypeScript functionality and best shared experience with this technology ive seen so far. And its not boring, even if i knew this stuff already. Like button clicked, good job buddy! Keep going. P. S I'm definitely waiting for OOP. That's going to be amazing.

Feeling this. I think it's the first clearly communicated TS tutorial that hasn't left me banging my head against the desk.

This video presented me to Typescript. After sometime learning it, I now have a full time job in development. Thank you very much. This and many other of your videos helped me so much to get were I am today.

Wow, thank you for this awesome intro to TypeScript! I have been working at an internship this summer, and yesterday I ran into some TypeScript. I had a background in JavaScript already, but I searched for a crash course just to be safe. This came up first, and in twelve minutes, I got a good handle!

This video was incredible. TS looked so complicated but I UNDERSTAND IT NOW. Ten minutes well spent. Thank you!

This video was incredibly helpful! I have known about TypeScript for a while but never really understood what its use was over plain JavaScript. Now I'll probably start using it more than JavaScript.

As I become a better programmer, your videos have become some of my favourites. You give a nice birds eye view that makes diving into documentation way easier!!!

Best concise beginners intro tutorial ever on typescript, with best practice! 😊 I like your no BS approach, straight to the point. 😊 You're blessed with the gift of teaching! Keep going 😊 We'll applaud you. 😊

These videos are Gold, 1. includes almost everything you need to know for day to day tasks. 2. to the point without wasting any time. 3. English is very clear to understand and words are chosen very wisely. 4. easily and useful example so you can understand code fast and better THANK YOU VERY MUCH

One of the best channels! I really like the way you explain, edit the videos and keep your screen clean. Please, keep that quality. I was planning to learn React, but since your videos are so cool I'm now thinking to learn angular. Just because wanna see more videos on this channel.

Its just AWESOME. Instead of 1-2 hours basics, you have covered most of typescript in just 12 minutes. Beginners should also go through this video so that they can jump off to other concepts in very less time. +1 for this short and sweet but effective video over Typescript. I have watched your other videos also , you are AWESOME man. Straight to the point and you have not more that 15-20 minute videos. Great job dude. Keep it up. Liked it.

I've been busy with C# and JS all day today. I'm basically burnt out and then RU-vid recommenced your video and I enjoyed every single second. TS has been something I've had my eye for a while and this video just made me want to go out and give it a go.

You absolutely crushed it in this video. You wasted no time explaining and covered quite a bit in the 12 minutes. Subscribed!

I fell in love with TypeScript almost as soon as I heard about it. An unexpected benefit of TypeScript is you can now learn C# very easily if you want to. The syntax are very similar.

I didn't want to learn Typescript but after applying for jobs and seeing it as a requirement, I had to check it out and I've become interested in it. It is super powerful and the learning is quite easy. The data typing is quite similar to Python’s code hinting and annotation. Glad I saw this vid.

Hey, great tutorial. Been using the ES6 version of JS in both frontend browser-based apps and backend NodeJS apps for some time now and whilst its marked improvement over prior versions (owning to the first class support for classes, objects and inheritance, etc) one thing that its missing, in my view, as an engineer used to working with fully fledged backend languages (I,e Java,Go,etc) , is Strong Typing. String Typing is useful for many of the reasons you cited in your video, principal among them: the ability to detect type mismatch (and related) errors at compile time rather than at runtime, which in and of it self may go some way to preventing the occurrence errors that can be incredibly difficult to reproduce and diagnose. I also love the fact that Typescript is essentially backwards compatible with JS, on account of it being a super set of the language; I may actually use Typescript on my next project and that is, in no small part, due to the clarity and intuitive exposition of this tutorial. Thank you!

Had a interview question about what was the difference between typescript and JavaScript and this video saved my life.

My man taught me hours of typescript in 12mins.

I have so many regrets as a junior developer. I contributed a bunch of angular 7 code at a startup I work at. I had no web development experience, but regardless I needed to finish my tasks as they're assigned, so I mostly focused my efforts on learning the Angular framework (which I absolutely love tbh) and the bare minimum JS. God the web project has gotten so big now, and I really wish I fully embraced the typescript... Future junior web devs out there, heed my warning: don't neglect TS! I feel like I'm stuck conforming to bad habits for the sake of consistency.

This video has the perfect pace and amount of information for people who know js and want to get into ts. awesome!

This Channel really really deserve more. This video is one of many successful videos on this channel to deliver big topic in few minutes. All respect.

I like your videos which forces me to focus more as it is in the perfect speed mode. Looking forward for the TypeScript Deep dives...

I would really love to see more of these videos, as I'm very new to TypeScript .

Thanks Jeff for an awesome content as usual. Love your tutorials and the way you explain. This was more useful.

Awesome video, this year I started working with TS and have grown to love it. 🤘🏻

Finally i really understand what is the use of and the [varname?] thank you for making this video. Please do the oop and functional programming for typescript

It's been 3 years now since the video was released, and we NEED an ADVANCED typescript crash course

Rocking it again! Absolutely smooth and most efficient intro to typescript.

This is the first time, I want to try working with Typescript. Great delivery.

The reason I love angular is because of Typescipt. Great intro to Typescript. Keep the videos coming

sooo smoothly edited video, I love these informative basic videos.

This was excellent. I would really love to see the object oriented/ functional programming in TS episode. That's been an object of curiosity for me lately.

Honestly best tutorials on RU-vid. I wish you made videos for advanced Javascript stuff not focused just around angular ;)

Love your articulated vids that get me started with new concepts n frameworks . Time to do some TS on my projects ☺️

This channel is low-key the best web dev value watch on youtube.

Another great video from Jeff. This video is great as a soft introduction to TypeScript, and why is it very useful. And for the next TS video, OOP in TypeScript will be "sequel" to this video.

I have been struggling for years in javascript and today i discovered this. I litterally looked up i hate weak typed js and found this. I'm so happy

Just the right amount of information in a good pace to give the understanding of basics.

I'm just thinking what should be my next step as a software engineer and I was thinking about TypeScript. Your tutorial really helped me feel that this is the direction i would like to go!

I'm newbie of Typescript and this help me a lot to understand the syntax and how is different from Javascript.

Thanks for the great video. Love the format. A video about decorators next would be awesome.

This was an amazing introduction to TypeScript. Thank you!

amazing ability to explain, clear, fast, concise, you should be a university professor :)

Great quick start guide! Exactly what I was looking for rather than a ~1 hour snoozefest 😴😴

This video rocks. Thanks for putting this out there. I'd like to see a video on decorators in TypeScript. Also, a video on NestJS would be awesome.

Learnt a lot from this, thanks. Would definitely like to see some more TypeScript videos!

Really loved the video, It would be really helpful if you make an entire series on typescript

Helpflul as always! Thanks Jeff for your content. Typescript is life, typescript is love! :)

Perfect thank you 👌 These videos are great for afternoons when you don't feel like reading through 500 pages of documentation but just want to get your hands dirty.

I would love to see some advanced typescript (also love the T-shirt)

really good video. it doesn't spam you with opinions and perspective. but actually show you stuff. great

A decorators follow up video would be great! Nice work again.

Amazing explanation, I subscribed right away. I hope to learn as much as I possibly can from your videos

This video was perfectly done! Loved it. Will try to use typescript in my new project

First time i watch one of your videos and feel like I'm ahead! And i have 22 years of JavaScript experience, feels good :)

This was very well done looking forward to object oriented vs functional programming

An excellent wrap-up of TS, short, sweet and up to the point. :-D

thanks so much for every single tutorial. I was smashing my head on the wall day and night and couldn't sleep well because I did not fix the error! thanks so much

Really good insight on Generics, finally understand how they work.

This video helped a lot. Like you, I didn't even want to start learning TypeScript, but I was kinda curious what it's all about. I'll now use TypeScript as well xD

Great intro video. Excellent examples that show the cause & effect. I could already infer the syntax mid-way thru the video.

First time looking into TS Thank you for this

I'm love with TS

One of the greatest advantages of people coming from the Angular 2 framework. To know TS out of the box. I love to use it with React and Node JS services and share models of objects back and forth in a mono repo.

Please do object oriented vs functional. Your videos are a great learning reference for me. Thanks!

JS devs that are hesitant to learn TS because of the "extra code" will realize the amount of time saved from out of the box auto-complete with documentation + compiler errors instead of nasty runtime errors is worth it 100 fold. Plus the extra code is only if you want to adopt typescript features....if you just decide to write vanilla javascript you can and you'll still get the benefit of the typescript compiler catching a lot of potential errors for you.

amazing video. Compact and very informational for anyone wanting to know what using Typescript is like

Incredible video. I definitely am starting to learn Typescript these days.

Very easily understandable language, Thank you.

Good video, much better than majority of the stuff I find on RU-vid for referencing.

As i said earlier, quality content is what you deliver always in your videos.

Like you, my main reason for getting started to learn TS is Angular. It's time to learn both, because I don't want to only know and use React. I was interested in trying NestJs for the backend too, but lacking of TS skill prevented me. I read that Deno supports TS too.

Best ! As always! Thanks a lot It would be great to see about OOP and FP in ts

This video was incredibly helpful, and I'd be interested in an OOP vs FP video as well. Also wanted to know if you are going to do any videos on Flutter.

Wow, Those 12 mins are the best 12 mins invested in my life ! I felt like I am on The Matrix. :-P Learn TS in 12 mins :-D Excellent video and very well explained the most important concepts.

Thanks for the video. I would like to see more advanced content about typescript.

Wow. I came here just to get an idea of differences now I actually want to research it and learn it.

Great video! Please continue the TS series.

This channel is on fire man. Thanks for making these videos :)

Love the channel, definitely made it into my subscriptions

This deserves more views

very similar to how php handles typing. love it. I didn't know that typescript was just extended javascript. that's actually amazing

Leant typescript in less 12 minutes, now that's how a tutorial should be done. Keep it up good work. A like and a sub from me

Thank you for this, finally got into TypeScript for all my JS, and WHOA, fixing bugs BEFORE running the page, lovely, now it's not too far from what I'm used to with other languages. Have not managed to get the watch task to run automatically yet, seems it should be working in VS Code but my config does nothing. Oh well, it's still golden, just that I keep forgetting to run said task 😅

I really love Typescript. Thank you Jeff for amazing explanation.

It's cool, i really like your videos with perfect voice and awesome animations. You should continue make content like that.

Thanks for the tips! I didn't know about the tuples in typescript

Wow this is simpler than I thought. Great tutorial.

Very nice video! Please do OOP vs functional next. Thank you for another great video!

Good video. Love this for making simple understanding in a short time

it was the best typescript crash course i've seen in youtube

Thank you for bringing great tutorials
