Benchmark: JavaScript spread operator vs create object performance vs destructuring

Tests:

Using the spread operator
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const finalObject = { ...firstObject, ...secondObject };
Create new object
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const finalObject = { sampleData: firstObject.sampleData, moreData: secondObject.moreData };
destructuring
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const {sampleData} = firstObject; const {moreData} = secondObject; const finalObject = { sampleData, moreData };
