If you refresh the page, you’ll see the contacts in the following order:
• Alice Tampen
• Alice Artsy
• Alice Arten
• Alice Smith
• Bob Brigham

What we’d like in this case, is to have them sorted by first name, then by last name in case of equality.
Look at the documentation³⁹ and see if you can figure out how to define a comparator function that

• Alice Smith
