var sDataArray = MultiDimensionalArray(2, 2);

function MultiDimensionalArray(iRows, iCols) {
    var i;
    var j;
    var table = new Array(iRows);

    for (i = 0; i < iRows; i++) {

        table[i] = new Array(iCols);

        for (j = 0; j < iCols; j++) {
            table[i][j] = "";
        }
    }
    return (table);
}

It looks like this function won't work when initializing arrays with more than 2 dimensions. – Anderson Green Jul 20 '13 at 19:52

var arr = [];
for(var i = 0;i<100;++i){
  arr[i] = [];
  for(var j = 0; j < 100; ++j){
    arr[i][j] = i*j;
  }
}

Its an array of arrays.

var arr = [

    [0,1,2],
    [3,4,5],
    [
        ['a','b','c']
    ]

];
