call vs apply (v38)

Revision 38 of this benchmark created by Mike Frey on

Setup

function Obj() {
      var that = "that";
    }
    Obj.prototype.target = function() {
    };
    
    var myObj = new Obj(),
        that = {that: "that"},
        arg = "arg",
        arg0 = "arg0", arg1 = "1", arg2 = "arg2", arg3 = "arg3", arg4 = "arg4",
        args = (function(){ return arguments; }(arg0, arg1, arg2, arg3, arg4));
