function lookUpProfile(name, prop){
// Only change code below this line

for( var i = 0; i < contacts.length; i++ ){
    if( contacts[i].firstName === firstName) {
        if( contacts[i].hasOwnProperty(prop) === true) {
            return contacts[i][prop];
            } else {
                return "No such property";
        return "No such contact";

// Only change code above this line

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

Link to the challenge:

What is firstName here?

You have neither defined nor you have firstName in arguments.

So, firstName is undefined.
You already have a variable in your function parameters which will help you reach the solution.

See if you can find that variable.

All the best.
