javascript - Calculate largest width of a set of elements using jQuery

Question

I have made a quick Jsbin: http://jsbin.com/ujabew/edit#javascript,html,live

What i'm trying to achieve is to find out which is the largest <section> out of the 3 from the link. So what i'd like is to, after the loop runs, is to have var width set to the largest possible number that any of the widths could be.

Answer 1

Here:

var maxWidth = Math.max.apply( null, $( elems ).map( function () {
    return $( this ).outerWidth( true );
}).get() );
