Benchmark: JavaScript spread operator vs Object.assign vs mutation performance with condition #4

Tests:

Using the spread operator
const firstObject = { sampleData: 'Hello world' } const finalObject = { ...firstObject };
Using Object.assign
const firstObject = { sampleData: 'Hello world' } const finalObject = Object.assign(firstObject);
Using mutation
const firstObject = { sampleData: 'Hello world' } const finalObject = { sampleData: firstObject.sampleData }
