Script Preparation code:

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}
var a = [...Array(10000)].map(_ => Math.random(1000000));
var ta = (new Int32Array(10000)).map(_ => Math.random(1000000));

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;
