small: DataView vs. native Object vs. native Array

Benchmark created on

Description

Compare the speed of different storage methods of multiple simple double (float64) types

Setup

const buffer = new ArrayBuffer(4*4);
const dv = new DataView(buffer);

const a = [0, 0, 0, 0];
const o = {a:0, b:0, c:0, d:0};

Test runner

Ready to run.
