I know it is wrong but for the past two days I don't know why,

Your code so far

var contacts = [
    "firstName": "Akira",
    "lastName": "Laine",
    "number": "0543236543",
    "likes": ["Pizza", "Coding", "Brownie Points"]
    "firstName": "Harry",
    "lastName": "Potter",

    "firstName": "Kristian",
    "lastName": "Vos",
    "number": "unknown",
    "likes": ["JavaScript", "Gaming", "Foxes"]

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

return contacts[i].prop
} else if ( name != contacts[i].firstName){
        return "No such contact"
} else if( prop != contact[i]){
    return "No such property"

// Only change code above this line

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