Benchmark: array to map and find small vs array find small

Script Preparation code:

var arr = Array.from({length: 100}).map((_,i) => ({id: i}));
var findTargets = Array.from({length: 100}).map((_,i) => idGen());
function idGen() {
  return Math.floor(Math.random() * 1000) % 1000
}

Tests:

array to map and find small
const arrMap = new Map(arr.entries()) findTargets.forEach(target => arrMap.get(target));
array find small
findTargets.forEach(target => arr.find(i => i.id === target));
