JavaScript - Array Object

The JavaScript Array class is a global object which is used to construct arrays. Arrays are list-like objects whose prototype has methods to perform traversal and mutation operations. The length of the JavaScript array and types of elements in it are not fixed. Therefore, the length of an array can change at any time, and data can be stored at non-contiguous locations in the array.
