Script Preparation code:
var a = [...Array(10000)].map(_ => Math.random()); var ta = (new Float64Array(10000)).map(_ => Math.random());
Tests:
array reverse
a.reverse();
typedArray reverse
ta.reverse();
array i/o
for (let i = 0; i < 10000; ++i) a[i] = a[i] + 1;
typedArray i/o
for (let i = 0; i < 10000; ++i) ta[i] = ta[i] + 1;
