Benchmark: Array vs TypedArray

Tests:

Array write
const a = new Array(0x1fff).fill(0); for(let i = 0; i < 0x1fff; i++) { for(let j = 0; j < 0x1fff; j++) { a[(i ^ j) & 0x1fff] = (i ^ j) & 0xff; } }
TypedArray write
const a = new Uint8Array(0x1fff); for(let i = 0; i < 0x1fff; i++) { for(let j = 0; j < 0x1fff; j++) { a[(i ^ j) & 0x1fff] = (i ^ j) & 0xff; } }
