• sorry, what? you mean you want to sort the arrays by their length? – gexicide Commented Jun 26, 2012 at 11:32
• I want to find out which one is the largest, the second largest, the third largest and the smallest in quantity. I need to assign them into above variables (please see my explanation) – Bayu Commented Jun 26, 2012 at 11:37
• I think when @gexicide said "What?" he meant that your explanation doesn't make a lot of sense, and he would like you to clarify it. – phenomnomnominal Commented Jun 26, 2012 at 11:40
• Ok. Yes, I want to sort the arrays by their length. How can I do that? – Bayu Commented Jun 26, 2012 at 11:43
• 1 In that case the second fiddle example is wrong. – Angel Commented Jun 26, 2012 at 11:50

Sorted by: Reset to default 12

var
  a = ["a", "a"];
  b = ["b", "b", "b", "b"],
  c = ["c", "c", "c"],
  d = ["d"],
  container = [a, b, c, d];

​container.sort(function (a, b) {
  return b.length - a.length;
});

console.log(container);

container will be sorted from longest (most elements) to shortest (least number of elements). Access it as:

container[0] // longest
container[1] // 2nd longest
// ...

You can find the length of the array using the length method and then sort these according to their values to find the largest, second largest array.
