Revision 3 of this benchmark created by GusC on October 23, 2013

Preparation HTML

<script>
function A() {
    this.sum = 0;
}
A.prototype.fn = function(x,y) {

   this.sum=x+y

   return this;
};
</script>

Setup

var a = new A();
    var sum = 0;
    var fn = function(x, y) {
      sum = x + y;
      return this;
    };
    
    var that = {};
    that.fn = fn;
    
    var fnBind = fn.bind(that, 1);

Teardown

    if (sum < 1 && a.sum < 1) throw new Error()
  

Test runner

that.fn(1, 1);

fn(1, 1);

fn.call(that, 1, 1);

fn.apply(that, [1, 1]);

fnBind(1);

a.fn(1, 1);
