Profile Lookup, hey saw the solution but was wondering what i swrong with my code i kinda think it should work

Tell us what’s happening:

Your code so far

//Setup
var contacts = [
    {
        "firstName": "Akira",
        "lastName": "Laine",
        "number": "0543236543",
        "likes": ["Pizza", "Coding", "Brownie Points"]
    },
    {
        "firstName": "Harry",
        "lastName": "Potter",
        "number": "0994372684",
        "likes": ["Hogwarts", "Magic", "Hagrid"]
    },
    {
        "firstName": "Sherlock",
        "lastName": "Holmes",
        "number": "0487345643",
        "likes": ["Intriguing Cases", "Violin"]
    },
    {
        "firstName": "Kristian",
        "lastName": "Vos",
        "number": "unknown",
        "likes": ["Javascript", "Gaming", "Foxes"]
    }
];


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

// Only change code above this line
}

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

Ok thanks, Using the same logic what do i need to change/modify/add/remove for it to work…or is it completely impossible to attack the problem from my(logical) angle
