Plz help me to get rid out of these

Tell us what’s happening:

Your code so far

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(name, prop){
// Only change code below this line
for(var i=0; i<contacts.length; i++){

if(contacts[i].firstname === name){
    return contacts[i][prop];}
    else{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:

What issues are you having?

  1. The property name is firstName not firstname

  2. What happens when the first if statement is false?

  3. What happens when you use the return keyword inside a for loop?

  4. How will you check the rest of the names when you have returned out of the for loop?
