Call vs. Apply

Today I'm going to tell you an educational story.

var f = function() {};

var test = function(callback) {
  var time = new Date();
  (10000).times(callback);
  console.log(new Date() - time);
};

var test_with_apply = function() {
  test(function() {
    f.apply(this, [0,1,2,3,4,5,6,7,8,9]);
  });
};

var test_with_call = function() {
  test(function() {
    f.call(this, 0,1,2,3,4,5,6,7,8,9);
  });
};

(10).times(test_with_apply);
console.log('--');
(10).times(test_with_call);

The moral
