Basic JavaScript - Profile Lookup

Hello guys I wanted to know why my code isnt working?
does anyone have any clue?

// Setup
const 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(name, prop){
  // Only change code below this line
for (const i = 0; i < contacts.length;i++){
  if (contacts[i].firstName === name){
    if (contacts[i].hasOwnProperty(prop)){
      return contacts[i][prop];
    } else {
    return "No such property";
return "No such contact";
  // Only change code above this line

lookUpProfile("Akira", "likes");

Link to the challenge:

is it because of const = i ???
also why I thought they were the same

Is there an error message?

Which ‘they’ might be the same?

yes it says all the test are false and i get in the console

`lookUpProfile(“Kristian”, “lastName”) should return the string Vos

lookUpProfile(“Sherlock”, “likes”) should return [“Intriguing Cases”, “Violin”]

lookUpProfile(“Harry”, “likes”) should return an array

lookUpProfile(“Bob”, “number”) should return the string No such contact

lookUpProfile(“Bob”, “potato”) should return the string No such contact`

let and const these I thought they were similar but const was better to use

You can’t change a const variable’s value but you can change a let. i should change

so const would be more appropriate to declare a global variable and let inside functions?

Use const everywhere you can. Only use let if the value of the variable needs to change

ok thank you for the information
