BigInt vs. number operations

Benchmark created on

Setup

const numbers = [];

for (let i = 0; i < 100000; i++) {
	numbers.push((Math.random() * 0xffffffff) & 0xffffffff);
}

const ints = numbers.map((x) => BigInt(x));

const operations = [
	(a, b) => a + b,
	(a, b) => a - b,
	(a, b) => a * b,
	(a, b) => a / b,
	(a, b) => a % b,
];

const program = Array.from({ length: numbers.length - 1 }, () => (Math.random() * operations.length) | 0);

console.log("e");
