There is a typo in the following file: javascript-exercises/05_joinStrings/joinStrings-example.spec.js

line 13:

The description of the test that checks if the last name is correct should be Stevenson instead of Carlos.

Right now it is:

  test('lastName is Carlos', () => {
    expect(values.lastName).toEqual('Stevenson');
  });

Should be:

  test('lastName is Stevenson', () => {
    expect(values.lastName).toEqual('Stevenson');
  });
