JQUERY: $(window).scrollTop(function() { $('.grid_12').find(function () { var $header = $(this); if ($header.off...

Should 'else' be kept or dropped in cases where it's not needed?

This is a sort of trivial question but something I've been wondering about. In terms of style (I assume the performance is identical), is it better to keep an 'else' in an if statement where it's not necessary? For example, which of the following is better: if (x < 10) doSomething(); else if (x > 20) doSomethingElse(); or if (...

Evaluating a boolean variable in PHP: Should one use If/Else or Switch?

I love getting myself into these ridiculous situations where I over-evaluate my coding practices, so here goes! This question probably transcends PHP (as well as sanity).
