Benchmark: Sync vs Promise benchmark test

Script Preparation code:

function foo() {
	const array = [];
  	const count = 1000000;
  	for (let i = 0; i < count; i++) {
    	array.push(Math.random() * count);
    }
    return array.filter(num => num > count / 2);
}

Tests:

Sync
const run = () => { const result = foo(); console.log(result); }; run();
Promise
const run = async () => { const promise = new Promise(resolve => { resolve(foo()); }); const result = await promise; console.log(result); } run();
