Tell us what’s happening:
Describe your issue in detail here.

It always returns “No such contact” even if name is present in the contacts array. Please help thank you.

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

lookUpProfile("Harry", "likes");

That is because you only ever check the first entry in the contacts array before returning a value. Remember that a return statement exits the function immediately even if the for loop has not completed.

Thank you for your help. I came up with a solution after some research.

This is my solution:

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) {
let result = contacts.find((x) => x.firstName == name);

if(!result){
  return "No such contact";
}
else {
  return result.hasOwnProperty(prop) ? result[prop] : "No such property";
}

}

console.log(lookUpProfile(“Harry”, “likes”));
