Tell us what’s happening:

How does this code work in simple explanation?

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
  let x = 0; 

 for (let 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"; 

  }
  // Only change code above this line
}

lookUpProfile("Akira", "likes");

Isn’t that the code you wrote? Which specific part are you confused about?

3

it’s not returning the correct answer.

lookUpProfile("Kristian", "lastName")

should return the string

Vos

lookUpProfile("Sherlock", "likes")

should return

["Intriguing Cases", "Violin"]

lookUpProfile("Harry", "likes")

should return an array

hi i think your problem is this line: return "No such contact";
try to put it in else if or otherwise it will not work, like

else if (contacts[x].firstName !== name){
  return "No such contact";

}
6

or just write that line outside for loop

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
