toBeA() function, throwing an 'undefined' error about expect HOT 2 CLOSED

What version of expect are you using? v21+ is now managed by jest

from expect.

Yes @ljharb , I'm using v21+
After going through the Readme Notice Github page, I found out the package has been donated to Facebook Jest, so i did a little search query on it, and fixed it with the code below:

it('should return the square of the number', () => {
  let res = utils.square(5);

  expect(res).toBe(25);
  expect(typeof res).toBe('number');
});

Thanks @ljharb

from expect.
