Answer 1

To create a 2D array in javaScript we can create an Array first and then add Arrays as it's elements. This method will return a 2D array with the given number of rows and columns.

function Create2DArray(rows,columns) {
   var x = new Array(rows);
   for (var i = 0; i < rows; i++) {
       x[i] = new Array(columns);
   }
   return x;
}

to create an Array use this method as below.

var array = Create2DArray(10,20);
