Benchmark: math on array vs float32array vs float64array - v2

Script Preparation code:

var a = [...Array(10000)].map(_ => Math.random());
var av2 = [...Array(10000)].map(_ => Math.random());
var ta32 = (new Float32Array(10000)).map(_ => Math.random());
var ta32v2 = (new Float32Array(10000)).map(_ => Math.random());
var ta64 = (new Float64Array(10000)).map(_ => Math.random());
var ta64v2 = (new Float64Array(10000)).map(_ => Math.random());

Tests:

array dot
let sum = 0.0; for (let i = 0; i < 10000; ++i) { sum += a[i] * av2[i]; }
Float32Array dot
let sum = 0.0; for (let i = 0; i < 10000; ++i) { sum += ta32[i] * ta32v2[i]; }
Float64Array dot
let sum = 0.0; for (let i = 0; i < 10000; ++i) { sum += ta64[i] * ta64v2[i]; }
