JavaScript performance comparison

Revision 24 of this test case created by max jooher

Info

Investigating the performance hit caused by nested functions.

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    var Closure = (function() {
    
      var store;
    
      function inner(a) {
        store = a;
      };
    
      return {
    
        Nested: function(a) {
          function inner(a) {
            store = a;
          };
          inner(a);
        },
    
        Unnested: function(a) {
          inner(a)
        }
      }
    })();
    
    
    var flat;
    
    function Nested(a) {
      function inner(a) {
        flat = a;
      };
      inner(a);
    };
    
    function Unnested(a) {
      inner(a);
    }
    
    function inner(a) {
      flat = a;
    };
  };
</script>
