Chapter 3: DOM Traversal Methods

Cause there's a train coming into the station
But it's heading for a new destination
    —Devo, "It Doesn't Matter to Me"

In addition to the selector expressions described in Chapter 2, jQuery has a variety of DOM traversal methods to help us select elements in a document. These methods offer a great deal of flexibility, even allowing us to act upon multiple sets of elements in a single chain, like so:

$('div.section > p').addClass('lit').lt(1).addClass('profound');

At times the choice between a selector expression and a corresponding DOM traversal method is simply a matter of taste, but there is no doubt that the combined set of expressions and methods makes for an extremely powerful toolset for getting anything we want.
