max/min Array vs Float32Array

Benchmark created on

Setup

const arr = [
	...Array(1000)
].map(e=>~~(Math.random()*1000))

const fArr = Float32Array.from(arr)

const findMinMax = arr => arr.reduce((p, c) => {
    p[0] = c < p[0] ? c : p[0] ?? c;
    p[1] = c > p[1] ? c : p[1] ?? c;
    return p;
}, [undefined, undefined])

const findMinMax2 = arr => {
  let min = arr[0];
  let max = arr[0];
  let i = arr.length;
    
  while (i--) {
    min = arr[i] < min ? arr[i] : min;
    max = arr[i] > max ? arr[i] : max;
  }
  return { min, max };
}
