Hash Tables | Data Structures in JavaScript 

Your hash collision is due to what I assume to be an unintentional bug in your hash function. Notice that the keys that resulted in the collision all ended with 'a'. That's odd. If you look inside the hash function, you'll notice that in the for loop, youre not updating hashedKey with +=, you're just reassigning it with =. This is the bug that resulted in your collisions. Keys whose last character ended in 'a' were all mapped to the same hash output.

this was super helpful! using the Map object was a game changer in trying to recreate them on my own

You easily explain those concepts... I m so happy to be here

Hey,Beiatrix,your code line 7 ,should be hashedKey += key.charCodeAt(i).

The chill bg music & the clear explanation are just ✨✨✨

this was really helpful, HashTable was an extremely difficult structure to grasp in college for me (along with graphs). But moving from java to JavaScript has made them really easy to udnerstand. thanks!

I laughed when you used "Sailor Moon" as an example here.LOL. I used to watch that anime as a child as well. Thank you for making this tutorial! Now, I have a better understanding of hash table.

wow i watched like three videos before this and was left even more confused than i was before, but when i watched your video somehow everything just clicked lol =D ty

Fighting evil by moon light, writing Maps by day light..... this was a great video! very concise and easy to under stand. think God for ES6

Great video but had to edit your code on repl because the for loop in the constructor of the HashTable class had 'this.buckets.length' instead of 'i < this.buckets.length'. It's correct in your video but only that was missing in the repl code. Besides that a lot of things clicked from watching your video! You definitely explained it in a more efficient and simple manner than the other videos i've watched.

Even if you dont speak or understand inglish very well, i got it all ... thanks for the vid.. Saludos desde Argentina. _V

Very nice and classy. Thank you.

wow....great explanation and easy to understand quickly compare to other videos. 🥰

Super well explained! I loved it! Thank you!

Your data structure playlist is great and appreciated! Lol the spongebob clip at the end of this video caught me off guard. It was funny. NICE lmbo! I like the use of Sailor Moon Lol. I felt like a kid again.

Thank u so much 💗

Why are you so good!? 🙃

i think the for loop is redundant here, you can just do hashedKey = key.charCodeAt(key.length-1) when generating hash or prob you meant hashedKey += key.charCodeAt(i) ? cheers!

Fantastic video... Very helpful. Thank you.

Great!

Please do more videos in js and programming

Unless I got it wrong, I think the downsize of Map is that, just like in an object, it will overwrite the value of a key in case the key already exists. It is kind of exceptional, because for that you should have collision, plus the same key, which is an exceptional case but it could as well happen. But for the purpose of explanation this logic is quite simple and easy to understand. For edge cases one should do ones own analysis.

Hi. good tutorial! in the link, in your code there is an error on line 17, the index of 'for' is missing for the iteration to end ... should be: for (let i = 0; i

Before this the mere mention of hash table gave me nightmares. Thanks

Lovely explanation. Here is my observation. The collisions occurred because all keys that ends with the same character, end up having same hashes. For instance a, aba, fjha, aaaaaa, .... all have same hash value. So why is it like that?

I found this to be super valuable thank you!

Cool, I am able to understand. Thank you.

Wow you still remember those names 😂 Is it weird that I use to watch that as we as a little boy after coming home from school? Oh well.

Hi Mam Awesome Video Please More video on JavaScript Api

Very well done. Thank you

Yeeeesss this was the best video i saw on this

Thank you! Well explained

Great tutorial! I also loved watching Sailor Moon!

Really great stuff. A thought, sometimes your use of let could be replaced by const - it seems.

I assumed that in JS Objects like {key:value} is already implemented, and in Python it’s called ‘dictionary’. Am I right?

I’m surprised you don’t have more subs

You are my savior. I love you XD

THANK YOU SO MUCH!

Thanks for this video :)

the slash bringing hasher?

you dont need a new Map per bucket? or is there an benefit?

What is the music ? I really love it . And thank you so much ❤️💕

At 6:07 you said "Lets peek at our hash table", how can I do that in the console?

The explanation was incredible, but the example she did could have been much better if she had done it from scratch.

what did you use to run your code? because I tried running it on scrimba and Vscode but I couldn't see the hash table on either.

Do you write with the left hand?

Cool video! btw stop smacking the keyboard lol

WOOOAAAAAAH YOUR LIPS ARE SOOOOO SHINY

How come there was a collision of 3 characters ? Is that just random?

I understand at least as well as Spongebob.

The music is pretty distracting in this one but thank you

Didn't knew Nicky Minaj is into programming.

كودك بخزي

But... you're just using an ES6 Map under the hood... you're not really implementing it yourself

hashbrown lol

Youre beautiful and smart :)))

Didn't really learn anything but just copied code :(

Are you a men

Great explanation but you are too pretty and it's distracting.
