Script Preparation code:

function getRandomInt(max) {
    return Math.floor(Math.random() * max);
}

var a = [...new Array(10000)].map(_ => getRandomInt(1000000));
var ta = (new Float64Array(10000)).map(_ => getRandomInt(1000000));

Tests:

array sort
a.sort();
typedArray sort
ta.sort();
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; }
typedArray i/o w convert back to array
for (let i = 0; i < 10000; ++i) { ta[i] = ta[i] + 1; } let tb = Array.from(ta);
create arrays
const a = []; for (let i = 0; i < 10000; ++i) { a.push([i]); }
create typed arrays
const a = []; for (let i = 0; i < 10000; ++i) { a.push(new Float32Array([i])); }
create typed arrays in typed array
const a = new Float32Array(10000); for (let i = 0; i < 10000; ++i) { a[i] = new Float32Array([i]); }
