Creation of two-dimensional array

JavaScript does not directly support two-dimensional arrays, but you can set the values of array elements to be equal to arrays so that you can simulate the structure of two-dimensional arrays.

Method 1 for defining two-dimensional arrays:

Var a = []; a [0pr 0] = 1th a [0je 1] = 2th a [1je 0] = 3th a [1je 1] = 4

Method 2 for defining two-dimensional arrays:

Var a = [/ / define a 2D array [1.1,1.2], [2.1,2.2]]

Method 3 for defining two-dimensional arrays:

Var a = new Array ([1.1,1.2], [2.1,2.2]); / / defines a 2D array
