Description

    for (var i = 0; i < 10000; ++i) {
      arr.push(1);
    }

forwards
for (var i = 0; i < arr.length; ++i) {
    for (var j = 0; j < arr.length; ++j) {
    }
}

backwards
for (var i = arr.length; i > 0; --i) {
  for (var j = arr.length; j > 0; --j) {
  }
}

Hard Coded Forward

Cached Forward Iteration
for(var i=0, c=arr.length; i<c; i++){
