Benchmark: JavaScript spread operator vs Object.assign performance 3

Tests:

Using Object.assign
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const finalObject = Object.assign(Object.assign(Object.create(null), firstObject),secondObject);
Using spread op
const firstObject = {sampleData: 'Hello world'}; const secondObject = {moreData: 'foo bar'}; const finalObject = {...firstObject, ...secondObject};
