No idea what that does. So I guess I'm not one of them 😂

@olback it iterates on an array. In an ugly way:

$.each(array, function (el) {
// do things
});

in place of:

array.forEach(function (el) {
// do things
});

Old IE compatibility ;)

For IE versions not even Microsoft supports.

Because Jquery.
Plus isn't array.foreach() still a prototype?

Why don't people just write a for() loop instead 🤷‍♂️

@lknk true, but this is JS, so it shouldn't be looping through thousands of indexes in the first place where the performance of a second temporary variable would have any actual impact.

forEach is an array method, $.each can be used on any type of collection.

They are very differently behaving methods.

What about Array.from(array).forEach()?

Well, it's longer to type, but you avoid importing a heavy library.

The alternative is knowing the fucking variable you are operating on and using the fucking appropriate method

As someone who's «forced» to use it, I use it simply because I have so much work and so little time that i can't focus on performance, I need to get things done ASAP.

@lknk If you're like me and shit at designing you're gonna implement bootstrap which comes with jQuery and if you already have it, why not use it?

@lknk yeah beause reading and writing 2 variables is quicker than a function call. Of course for() is faster than foreach. Always. By fucken definition.

@C0D4 @lknk u guys know that for is superior in speed to forEach. For is faster and hard to beat for forEach.
