Like so:

JavaScript

var array = new Array(12);
for (var i = 0; i < 12; i++) {
  array[i] = new Array(18);
}

Will this give me: array[1, 1]="Something";

[no name] 4-Jul-18 14:12pm

You would assign it like so:

array[1][1] = "Something";

I am getting as error on : var array = new Array(12);

[no name] 4-Jul-18 14:18pm

What is the error? The syntax is correct, have a look here: http://jsfiddle.net/uo5d8zk9/

The first answer is a perfectly valid answer. Just thought I might add the alternate syntax version:

JavaScript

var ax2 = [12];
for (var i = 0; i < ax2.length; i++) {
  ax2[i] = [18];
}
ax2[0][0] = 23*38;
alert(ax2[0][0]);
