Using toBe and toNotBe to compare array/objects

We'll start with removing the current code by commenting it out. We'll leave it around so we use it later:

it('should expect some values', () => {  // expect(12).toNotBe(12);});

We'll expect an object with the name property set to Andrew, toBe, and we'll assert that it is another object where the name property is equal to Andrew, just like this:

it('should expect some values', () => {  // expect(12).toNotBe(12);  expect({name: 'Andrew'})});

We'll use toBe, just like we did with number, checking if it is the same as another object where name equals Andrew:

it('should expect some values', () => {  // expect(12).toNotBe(12);  expect({name: 'Andrew'}).toBe({name: 'Andrew'});});
