Simple null bind vs closure (v3)

Revision 3 of this benchmark created on

Setup

A = [];
    
    function set(i, v) {
      A[i] = v;
    }
    todo = [];
    
    function plan(f) {
      todo.push(f);
    }
    
    function go() {
      var i = 0,
        l = todo.length;
      for (i = 0; i < l; ++i) {
        todo[i]()
      }
    }

Teardown


    A.length = 0;
    todo.length = 0;
