Closure Prototype Static Performance

JavaScript performance comparison

Test case created by Colin Kraebel

Info

Test based on this SO question: Javascript prototype operator performance: saves memory, but is it faster?

Preparation code

 
<script>
Benchmark.prototype.setup = function() {
    function X() {};
    X.prototype.message = function(s) {
      var mymessage = s + "";
    };
   
    X.prototype.addition = function(i, j) {
      return (i * 2 + j * 2) / 2;
    };
   
   
    function Y() {
      this.message = function(s) {
        var mymessage = s + "";
      }
      this.addition = function(i, j) {
        return (i * 2 + j * 2) / 2;
      }
    };
   
    Z = {
      message: function(s) {
        var mymessage = s + "";
      },
      addition: function(i, j) {
        return (i * 2 + j * 2) / 2;
      }
    };
};
</script>
