.closest()

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

.promise()

Return a Promise object to observe when all actions of a certain type bound to the collection, queued or not, have finished.

.find()

Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

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.

.text()

Get the combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.
