Kyle proves again, its not about inventing the methods shown, but telling the programmers about it. Absolutely essential skills.

One thing to note is the support for 'at' in older browsers

It's like list indexing in python. Finally, they are doing it. Always wanted to have python-like indexing and slicing in JS xD

sultanmuammad

Implementing our own at is good option.

Very useful. Thx a lot for highlighting this.

That's pretty good... I didn't know this array function exists. Thanks!

when he showed .at(), at first i thought "cant you just use a regular index for that?" until he showed that negative numbers can be passed in too

one caveat is it cannot be used to set value, i.e arr.at(-1) = 1 will not be allowed.

Subscribed. Thank you for this content. I hope you're covering Typescript as well

Meanwhile Python lets you do the very same thing using normal brackets notation

tomershechner

I would have never known you could do that if not this video. I’ve always like Python better because it just lets you do this normally like any good language should but it’s good to know that JS kinda lets you do the same.

new thing we added to our mind library

What if the length was zero? Error or undefined? Is this the same behavior you would expect if you used length - 1?

LostnTranslation

Meanwhile kotlin: names.first(), names.last()

rudemption

This method is not supported for example on ios 14. And for some reason creat react app did not polyfill this method so website did not work on iphone
