Your code so far

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

// Change these values to test your function
lookUpProfile("Akira", "likes");

Your code has several issues, but the line above is one of the first.

When you use dot notation with the .prop above, you are trying to reference an actual property named “prop”. There are no objects with a property named “prop”, so you this if statement will never evaluate to true.

The other overriding issue with your code is that your for loop will only make a single iteration before you return something. Once a return statement is executed, the function immediately exits and does not come back to finish a loop.

Thank you so much for your reply. I’ll try changing my code.
