  for (let i = 0; i < contacts.length; i++) {
    if (contacts[i].firstName === name) {
      return contacts[i][prop] || "No such contact";
    }

Try to imagine the problem like this:
you have a book with a contact on each page.
You want to search for a specific contact and find a certain info
How do you search for that contact?

  • when do you know that the info is not there?
  • when do you know that the contact is not there?

I looks like i was running the else statement inside the loop, i mean it has to be right after the if statement but the problem is that the return cannot be inside the loop i needed to take it out side the loop and then close the close the else braces in order for this to work. I didnt know that and they didn’t splaying that in the description.

But anyways thank you very much for your help you have been great. have a nice day\evening\night.
