Multiple loops	3331.1 Ops/sec
Single loop	16803.3 Ops/sec

Script Preparation code:

const numbers = Array.from({ length: 10_000 }).map(() => Math.random())

Tests:

Multiple loops
const result = numbers .map(n => Math.round(n * 10)) .filter(n => n % 2 === 0) .reduce((a, n) => a + n, 0)
Single loop
const result = numbers.reduce((a, n) => { if (n % 2 === 0) return a; return a + n; }, 0);
