.data()

Store arbitrary data associated with the matched elements or return the value at the named data store for the first element in the set of matched elements.

jQuery.each()

A generic iterator function, which can be used to seamlessly iterate over both objects and arrays. Arrays and array-like objects with a length property (such as a function’s arguments object) are iterated by numeric index, from 0 to length-1. Other objects are iterated via their named properties.

.finish()

Stop the currently-running animation, remove all queued animations, and complete all animations for the matched elements.

.map()

Pass each element in the current matched set through a function, producing a new jQuery object containing the return values.
