Benchmark: JavaScript reduce vs Object.assign performance

Tests:

Using reduce
const firstObject = { '...': true } const arrayOfObjects = [{ moreData: 'foo bar' }, { evenMore: 'data' }] const finalObject = arrayOfObjects.reduce((result, object) => ({ ...result, ...object }), { '...': true })
Using Object.assign
const firstObject = { '...': true } const arrayOfObjects = [{ moreData: 'foo bar' }, { evenMore: 'data' }] const finalObject = Object.assign(firstObject, ...arrayOfObjects);
