Setup

var testSize = 2000;
    
    var ui8 = new Uint8Array(testSize);
    var i8 = new Int8Array(testSize);
    var ui16 = new Uint16Array(testSize);
    var i16 = new Int16Array(testSize);
    var ui32 = new Uint32Array(testSize);
    var i32 = new Int32Array(testSize);
    var f32 = new Float32Array(testSize);
    var f64 = new Float64Array(testSize);
    
    var array = new Array(testSize);
    
    var obj = {};
    var i = testSize; while(i--) obj[i] = 0;

Test runner

for(var i = 0; i < testSize; i++) ui8[i] = i*2;

for(var i = 0; i < testSize; i++) i8[i] = i*2;

for(var i = 0; i < testSize; i++) ui16[i] = i*2;

for(var i = 0; i < testSize; i++) i16[i] = i*2;

for(var i = 0; i < testSize; i++) ui32[i] = i*2;

for(var i = 0; i < testSize; i++) i32[i] = i*2;

for(var i = 0; i < testSize; i++) f32[i] = i*2;

for(var i = 0; i < testSize; i++) f64[i] = i*2;

for(var i = 0; i < testSize; i++) array[i] = i*2;

for(var i = 0; i < testSize; i++) obj[i] = i*2;
