Script Preparation code:

var a = [...Array(10000)].map(_ => Math.random());
var ta = (new Float64Array(10000)).map(_ => Math.random());
var tb = (new Float32Array(10000)).map(_ => Math.random());

Tests:

array reverse
a.reverse();
Float64Array reverse
ta.reverse();
array i/o
for (let i = 0; i < 10000; ++i) a[i] = a[i] + 1;
Float64Array i/o
for (let i = 0; i < 10000; ++i) ta[i] = ta[i] + 1;
