Benchmark: new set vs reusing set

Tests:

new set
const create = () => { const set = new Set() for (let i = 0; i < 1000; ++i) set.add(i) return set } for (let i = 0; i < 100; ++i) { const result = create() }
reuse set
const set = new Set() const create = () => { set.clear() for (let i = 0; i < 1000; ++i) set.add(i) return [...set] } for (let i = 0; i < 100; ++i) { const result = create() }
