Revision 10 of this benchmark created on October 26, 2013

Setup

var obj = {
      x: 10,
      y: 15,
      z: 20
    };
    
    var _obj = {};
    
    var a = 10;
    var b = 15;
    var c = 20;
    
    var arr = [10, 15, 20];
    
    var f32 = new Float32Array(arr);
    var f64 = new Float64Array(arr);
    
    var i8 = new Int8Array(arr);
    var i16 = new Int16Array(arr);
    var i32 = new Int32Array(arr);
    
    var ui8 = new Uint8Array(arr);
    //var ui8c = new Uint8ClampedArray(arr);
    var ui16 = new Uint16Array(arr);
    var ui32 = new Uint32Array(arr);
    
    
    var _arr = new Array(3);
    
    var _f32 = new Float32Array(3);
    var _f64 = new Float64Array(3);
    
    var _i8 = new Int8Array(3);
    var _i16 = new Int16Array(3);
    var _i32 = new Int32Array(3);
    
    var _ui8 = new Uint8Array(3);
    //var _ui8c = new Uint8ClampedArray(3);
    var _ui16 = new Uint16Array(3);
    var _ui32 = new Uint32Array(3);
