Javascript Basics "Profile Lookup" - I have set up everything but it doesn't output anything

Hi guys,

I’m doing the Profile Lookup Function right now. Where you have to find contacts in an json object.
Here is my code so far:

function lookUpProfile(firstName, prop){
// Only change code below this line
  for (var i = 0; i < contacts.length; i++) {
    
      if(contacts[i].hasOwnProperty(prop) && (contacts[i].firstName === firstName)) {
        return contacts[i].prop;
      } else if(!(contacts[i].hasOwnProperty(prop))) {
        return "No such property";
      }    
    }
    return "No such contact";
// Only change code above this line
}

In the screenshot you can see the output (none) and the test cases (just 2 passes).

Why are the other tests not passing? In my mind that function makes perfect sense. What did I do wrong?

Thanks guys!

try accessing the object using bracket noation instead of dot return contacts[i][prop] .when you use dot, javascript interprets prop as text instead of variable.

Yes that’s it thank you.
I was just wondering because FCC Editor gave a warning “is better written in dot notation”.
Anyway it’s working now thx :slight_smile:
