Benchmark: filterMap vs reduce (reduce with return on if)

Tests:

filterMap
const arr = new Array(52400).fill(null).map(() => Math.random()); for(let i = 0; i < 1000; i++) { const res = arr.filter(el => el % 2 === 0).map(el => el + 1).sort((a, b) => a - b); }
reduce
const arr = new Array(52400).fill(null).map(() => Math.random()); for(let i = 0; i < 1000; i++) { const res = arr.reduce((acc, el) => { if(el % 2 === 0) { return [...acc, el] } return acc; }, []).sort((a, b) => a - b); }
