Script Preparation code:

function getRandomInt(max) {
    return Math.floor(Math.random() * max);
}

var a = [...new Array(10000)].map(_ => getRandomInt(1000000));
var ta = (new Float32Array(10000)).map(_ => getRandomInt(1000000));

Tests:

Regular array
for (let i = 0; i < 10000; ++i) { a[i] = a[i] + 1; }
Float32Array
for (let i = 0; i < 10000; ++i) { ta.set(ta[i] + 1,i); }
