Script Preparation code:
const array = Array.from({ length: 10 }, () => Math.random()); const arrayObject = Array.from({ length: 10 }, () => ({ value: Math.random() })); const map = new Map(); const mapObject = new Map(); array.forEach((v, i) => map.set(v, i)); arrayObject.forEach((v, i) => map.set(v, i)); const testArray = _.shuffle(array); const testArrayObject = _.shuffle(arrayObject);
Tests:
Array.indexOf
testArray.forEach(v => { const index = array.indexOf(v); });
Map.get
testArray.forEach(v => { const index = map.get(v) ?? -1; });
Array.findIndex
testArray.forEach(v => { const index = array.findIndex(vv => v === vv); });
Array.indexOf Object
testArrayObject.forEach(v => { const index = arrayObject.indexOf(v); });
Map.get Object
testArrayObject.forEach(v => { const index = mapObject.get(v) ?? -1; });
Array.findIndex Object
testArrayObject.forEach(v => { const index = arrayObject.findIndex(vv => v === vv); });
