Remarks

A NodeList is a sort of array which is used to contain a collection of nodes. It is commonly used throughout the DOM objects as a way of returning a list of nodes, whether as a listing of Node.attributes bound to an Element, or as a list of Node.childNodes.

Though in principle this object is similar to an Array, it is merely a very rudimentary form, and as such there is no relationship between the two objects. The list of methods and properties a NodeList supports is quite small in comparison.
