Why return contacts[x][prop]?

Tell us what’s happening:

I know all code but why return contacts[i][prop];
we return a two dimensional array?

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) {
for (var x = 0; x < contacts.length; x++) {
    if (contacts[x].firstName === name) {
        if (contacts[x].hasOwnProperty(prop)) {
            return contacts[x][prop];
        } else {
            return "No such property";
return "No such contact";
// Change these values to test your function
lookUpProfile("Akira", "likes");

Not sure what you are asking. It is just returning the likes array.

we can just return prop.

I still don’t get it. The parameter prop is just passed a string.

Can you give an example of what you mean?
