Basic JavaScript - Profile Lookup

JavaScript
1

So it looks as though my code is iterating through each array based on my for loop, however it only recognizes whatever index number is in the for loop. What I mean is, when I change the for loop to x = 1, it recognizes Harry and all of its properties, but it gives Akira and all of the other profiles in the array “No such contact” in the console log.

I’ve tried tweaking a couple of things which didn’t do anything, but I can’t figure out for the life of me why it’s not working. I checked the video and it made sense and seems like I did it right, but the function will only work on 1 element in the array of contacts. Does anyone know why it’s not working?

Your code so far

// 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 (let x = 0; x < contacts.length; x++) {
  if (contacts[x].firstName === name) {
    return contacts[x][prop] || "No such property"; 
  } else return "No such contact";
}
  // Only change code above this line
}

lookUpProfile("Sherlock", "likes");
console.log(lookUpProfile("Sherlock", "likes"));

Having this inside of the loop effectively says “if you find a single contact that doesn’t match, give up, stop the loop, and return immediately”.
