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

// Only change code above this line

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

Link to the challenge:

let’s say you are looking for Harry Potter… when i is 0, contacts[i].firstName is Akira
so "Harry" !== "Akira" is true and No such contact is returned
