The best way to loop over an array in Javascript #shorts

I usually use the for of loop whenever possible since it works with async / await.

other thoughts to consider. the former way allows you start at any index in the array.

love the content. This would be the content I would make if I wasn't too lazy to start a channel lol

Just remember to use const instead of let so you don't end up changing the variable's value by accident

[laodemuhammadalfatih]

Use forEach, map, filter, etc for declarative approach, and for loop, while for imperative approach.

Surprisingly, I prefer the longer version for certain situations. Sometimes you may want to count down rather than up. Also, JS feels better when it's verbose in some situations like using a regular function over an arrow function when declaring a function but definitely using an arrow function as a callback. Or is it just me?

i use to use fof, but eslint gives a lot of warnings to iterate, and doing a small research there is a BIG difference between a classic for, and a fof, fin, for each, and more

The traditional for loop is faster than other iterating methods such as while, for..of and for..in

In 5 years of using JS professionally, I have needed a classic for loop once. I still wouldn't really recommend using that type of foreach shown in the video, i'd rather use `array.forEach((element, index) => { doStuff });`

or if possible, reduce, some, every and similar are even better

I still do prefer the non imperative array.forEach(); and if you want to start from a point in an array just use slice() with it ( you can even do range with this setup )
[1, 2, 3, 4, 5].slice(1, 4).forEach(el => console.log(el)); // 2, 3, 4

And if you need access to indices, you could do:

for (const [idx, number] of numbers.entries()) {}

Came from Python and it's a pretty good equivalent to enumerate()

No idea about performance though

[soulking]

It's only for rendering data but for filtering data i think we need to use first method. Btw noice short cut

[accidentalengineering]

for...of works on every Iterable, and arrays are iterable :)

[pandasoli]

the best way is probably using forEach

[SyberiaK]

In Python you can use *for number in numbers:*

how would you reverse it? similar to doing a for (let I = array.length-1; I >= 0; i--)

[soniablanche]

I only use "for of" if I have to use "await" inside a loop, otherwise I prefer array.forEach

[Notoriousjunior]

let x of xx is only good for readability. It doesn’t have the best performance if you’re processing large data.

[adrisongomez]

Video idea: Diff between for await and for...

[theofanisbirmpilis]

Is there a point to doing loops this way? Isn't it always better to use the array methods? Btw love the content keep on going bro

[ZeroSleap]

This is available in most i guess dynamic languages.

[juanpunch]

The same as forEach right? And for(i in array) ??
