$('elems').each() with fat arrow

Question

I started to use ES6 fat arrow function notation and I really like it. But I am a little bit confused about it context. As far as I know, keyword this inside fat arrow funct

Answer 1

Because this in the arrow function context is the same as the calling context.

The each function provides a current element as the second argument to the callback so

$('ul#mylist > li').each((i, el) => {
  $(el).addClass('some-class-name');
});

Or in the given case there is no need to loop

$('ul#mylist > li').addClass('some-class-name');
