Benchmark: Int vs string split

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

// Initialization
const N = 10000;
const numbers = new Int32Array(N);
for (let i = 0; i < N; i++) {
    numbers[i] = Math.floor(Math.random() * 1000000);
}

// Pack into ArrayBuffer for getInt32
const buf = new ArrayBuffer(N * 4);
const view = new DataView(buf);
for (let i = 0; i < N; i++) {
    view.setInt32(i * 4, numbers[i], true);
}

// Pack into comma-separated string for split
const csv = numbers.join(",");

Tests:

Integer
let sum = new Array(N); for (let i = 0; i < N; i += 2) { sum[i]=view.getInt32((i) * 4, true); sum[i+1]=view.getInt32((i+1) * 4, true); }
CSV
let sum = 0; const parts = csv.split(",");
