Instantiate 2d Array Javascript

In JavaScript, an Array is a dictionary that maps indices to elements It can have holes – indices between zero and the length, that are not mapped to elements (“missing indices”) For example, the following Array has a hole at index 1 > Objectkeys('a',, 'c') '0', '2' Arrays without holes are also called dense or packed Dense.
