Implement Multiple Dimensional Arrays In JavaScript Part IV of Array Series
An array specifies a variable that can be indexed as a list in rows and columns. A multidimensional array at allows storing and accessing data in a table-like structure with more than one dimension.
The first index is zero as is common in most programming languages. JavaScript objects can be used as associative arrays.
An array is a data structure consisting of a collection of elements which are values or variables.
