Benchmark: object[]: findIndex vs for loop with more complex condition check

Script Preparation code:

var length = 1e3
var arr = Array.from({length},(_,i) => ({id: i, rand: i * Math.random()}));
var target = Math.floor(length * Math.random());

Tests:

findIndex
let outIdx1 = arr.findIndex((x) => x.id > target && x.rand > length/3 && Math.random() > .5 ); /*console.log('findIndex',outIdx1)*/
for loop
let outIdx2 = -1 for (let i = 0; i < arr.length; i++) { if (arr[i].id > target && arr[i].rand > length/3 && Math.random() > .5) { outIdx2 = i break } } /*console.log('for loop',outIdx2)*/
