Tests:

Test Spread operator

const firstObject = { 
  	sampleData: 'Hello world',
	sampleMethod: () => { return true; }
};
const secondObject = {...firstObject};

 
const firstObject = {     sampleData: 'Hello world',    sampleMethod: () => { return true; }};const secondObject = {...firstObject};

Test Object.create

const firstObject = { 
  	sampleData: 'Hello world',
	sampleMethod: () => { return true; }
};
const secondObject = Object.create(Object.getPrototypeOf(firstObject), Object.getOwnPropertyDescriptors(firstObject));

 
const firstObject = {     sampleData: 'Hello world',    sampleMethod: () => { return true; }};const secondObject = Object.create(Object.getPrototypeOf(firstObject), Object.getOwnPropertyDescriptors(firstObject));

Test Object.assign

const firstObject = { 
  	sampleData: 'Hello world',
	sampleMethod: () => { return true; }
};

const secondObject = Object.assign({}, firstObject);
Object.setPrototypeOf(secondObject, Object.getPrototypeOf(firstObject));
