Profile Lookup - I feel i'm missing something small

I feel as though i’m so close, but just missing one or two small things here. Can someone guide me in the right path?

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

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

Take the first test case lookUpProfile("Kristian", "lastName"); and go through your code.
Explain step by step what happens at every if, else if statement.

Sometimes we need to use square brackets [ ] to access object properties, rather than .

I cleaned up your code.
You need to use triple backticks to post code to the forum.
