Benchmark: Object.assign vs. creating new objects3

Tests:

Object.assign
let Program = {a: "test", b: "neu"} let vorlage = { program: Program, currentStepList: [], stepIndex: 0, stackBase: 0, callbackAfterFinished: null, exceptionInfoList: [] } let list = []; for(let i = 0; i < 10000; i++){ list.push(Object.assign({}, Program)); }
create objects
let Program = {a: "test", b: "neu"} let vorlage = { program: Program, currentStepList: [], stepIndex: 0, stackBase: 0, callbackAfterFinished: null, exceptionInfoList: [] } let list = []; for(let i = 0; i < 10000; i++){ list.push({ program: Program, currentStepList: [], stepIndex: 0, stackBase: 0, callbackAfterFinished: null, exceptionInfoList: [] } ); }
