HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

var arrayToSort = [];

function getRandom() {
  return Math.random() * 10 % 10;
}

for (var i = 0; i < 10000; ++i) {
  arrayToSort.push({ a: getRandom(), b: getRandom() });
}

Tests:

sort by array
arrayToSort.sort(function(a, b) { a = [ a.a, a.b ]; b = [ b.a, b.b ]; return a < b ? -1 : 1; });
sort by string
arrayToSort.sort(function(a, b) { a = a.a + ':' + a.b; b = b.a + ':' + b.b; return a < b ? -1 : 1; });
