jQuery each() - How does it work really internally? [closed]

Answer 1

As far as I'm aware, this

$('selector').each(func);

is the equivalent of doing this:

func = ...;
$selector = $('selector');
for (var i = 0; i < $selector.length; i++) {
    if (func.call($selector[i], i, $selector[i]) === false) {
        break;
    }
}

The object returned by a $ selection is actually an array of DOM elements with a whole bunch of extra methods attached to it, so you basically can work with it just like you would an Array. Hope that clears things up!
