        "number": "0543236543",
        "likes": ["Pizza", "Coding", "Brownie Points"]
        "firstName": "Harry",
        "lastName": "Potter",
        "number": "0994372684",
        "likes": ["Hogwarts", "Magic", "Hagrid"]
        "firstName": "Sherlock",

function lookUpProfile(firstName, prop){
// Only change code below this line
var arrayLength = contacts.length;
for (i=0; i <= arrayLength; i++){
  if(firstName == contacts[i].firstName){
      return contacts[i][prop];
      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:

You have a problem in your logic which is causing you to check the first object in the contacts array before returning a value of some kind. Remember, once a return statement is executed, the function immediately exits and does not finish iterating through any loop.

HINT: Think about where you should really be returning “No such contact”.

Also, your for loop is not quite right yet:

for (i = 0; i <= arrayLength; i++) {

First of all, you need to always declare your variables used in your code. You have not declared i. Also, since arrays are zero-indexed, think what your for loop condition should really look like.
