Tests:
Test Spread operator
class firstObject { constructor() { this.sampleData = 'Hello world', this.sampleMethod = () => { return true; } } }; const secondObject = {...firstObject}; Object.setPrototypeOf(secondObject, Object.getPrototypeOf(firstObject));
Test Object.create
class firstObject { constructor() { this.sampleData = 'Hello world', this.sampleMethod = () => { return true; } } }; const secondObject = Object.create(Object.getPrototypeOf(firstObject), Object.getOwnPropertyDescriptors(firstObject));
Test Object.assign
class firstObject { constructor() { this.sampleData = 'Hello world', this.sampleMethod = () => { return true; } } }; const secondObject = Object.assign({}, firstObject); Object.setPrototypeOf(secondObject, Object.getPrototypeOf(firstObject));
Test New Object
class firstObject { constructor() { this.sampleData = 'Hello world', this.sampleMethod = () => { return true; } } }; const secondObject = new firstObject();
