typed Array vs JS Array vs Object

Benchmark created by Corey Clark on

Description

Testing computational speed for using Typed Array, JSON Array Object and JS Object

Setup

var typed = new Float32Array([1.0,2.0,3.0]);
    
    var array = [1.0,2.0,3.0];
    
    var obj = {
        x: 1.0,
        y: 2.0,
        z: 3.0
    }

Test runner

Ready to run.
