var arr = new Array(1500000).fill(0); for (let i=0; i<arr.length; i++) { arr[i] = arr[i] + 1; }
Uint8Array
var arr = new Uint16Array(1500000).fill(0); for (let i=0; i<arr.length; i++) { arr[i] = arr[i] + 1; }
Uint16Array
var arr = new Uint16Array(1500000).fill(0); for (let i=0; i<arr.length; i++) { arr[i] = arr[i] + 1; }
Uint32Array
var arr = new Uint32Array(1500000).fill(0); for (let i=0; i<arr.length; i++) { arr[i] = arr[i] + 1; }
BigInt64Array
var arr = new BigInt64Array(1500000).fill(0n); for (let i=0; i<arr.length; i++) { arr[i] = arr[i] + 1n; }
