Best Practices: Optimizing Selectors

Here are some tips to keep in mind when using selectors:

Id selections are really fast. They are handled by document.getElementById()

// This is fast
$('#statuses .status');

//This is faster

Sizzle, the jQuery selector engine works bottom-up (right to left). Be more specific on the right side of your selector rather than on the left

$('li.status .delete');

$(‘.status img.delete’);
