title: Alternatives to javascript function-based iteration (e.g. jQuery.each())
body: <p>I've been watching Google Tech Talks' <a href="http://www.youtube.com/watch?v=mHtdZgou0qU" rel="nofollow noreferrer">Speed Up Your Javascript</a> and in talking about loops, the speaker mentions to stay away from function-based iterations such as jQuery.each() (among others, at about 24:05 in the video). He briefly explains why to avoid them which makes sense, but admittedly I don't quite understand what an alternative would be. Say, in the case I want to iterate through a column of table cells and use the value to manipulate the adjacent cell's value (just a quick example). Can anyone explain and give an example of an alternative to function-based iteration?</p>
