make equal rows from a list

make_rows_from_list.js

(function () {
  inputList = [0, 1, 2, 3, 4, 5, 6, 7, 8];
  ouputList = [];
  makeRowsFromList = function makeRowsF(inputList, outputList, colsNum) {
    var i, len;
    outputList = outputList || [];
    len        = inputList.length;
    for (i = 0; i < len; i += colsNum) {
      outputList.push(inputList.slice(i, i + colsNum));
    }
  };
  makeRowsFromList(intputList, outputList, 3);
}());

Make equal rows from a list

just a simple function that takes a list like this:

[0, 1, 2, 3, 4, 5, 6, 7, 8]

And turn it into a list like this:

[[0, 1, 2], [3, 4, 5], [6, 7, 8]]

I made this to be used as a methode to group a list into equaly devided rows to be used with
bootstrap Grid system and AngularJS ngRepeat directive.
