If the name matches the name of the first contact in your array of contacts, and the contact has the property matching prop, this works.

The first if will be true, and the function will return the value of the property.

What happens if the name given to the function doesn’t match the first contact? What does return do?

but there is one thing why did we have to put the return “no such contact” outside of the loop

Well, what happens in your original code once it’s checked the first contact (regardless of whether it’s a matching name or not)?
