var a  = new Array(2);  

for 2 dimensional array, you can do the following:
var a  = new Array(2);  

for (i=0; i <4; i++)
a[i]=new Array(4)

2. Its not multidimensional array. To create multidimensional one:

The declaration is syntactically correct, however it's not a bi-dimensional array. What you created is an array with two elements - 2 and 4. If you want a bi-dimensional array you should do the following:

a=new Array(new Array(4), new Array(4));
