Tests:
new TypedArray
let arr = new Float32Array(1000000); arr[0] = Math.random(); for (let i = 0; i < 1000000; i++) { arr[i] = arr[i - 1]; }
new Array
let arr = new Array(1000000); arr[0] = Math.random(); for (let i = 0; i < 1000000; i++) { arr[i] = arr[i - 1]; }
Direct Array
let arr = []; arr[0] = Math.random(); for (let i = 0; i < 1000000; i++) { arr[i] = arr[i - 1]; }
