Question

A couple questions:

1. Is a regular javascript loop (to loop through a series of elements) faster/more efficient than using jQuery each() ??

2. If so, what is the best way to write the following code as a regular javascript loop?

$('div').each(function(){ //... })

Answer 1

Yes, removing the each() will give you slightly better performance. This is how you could write a for loop for a list of elements.

var divs = $('div');

for(var i = 0; i < divs.length; i++){
    var thisDiv = divs[i]; // element

    var $thisDiv = $(divs[i]); // jquery object

    // do stuff
}
