Tell us what’s happening:

Hey, my code passes all the tests presented, except the lookUpProfile(“Sherlock”, “likes”) should return [“Intriguing Cases”, “Violin”] one, my code outputs [ ‘Intriguing Cases’, ‘Violin’ ].

How should I fix that?

Your code so far

let 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 = ""
  let resultArr
  let index = 0
  for (const contact of contacts){
    if (contact.firstName === name || contact.lastName === name) { 
      break
    } else index++; 
  };
  if (index >= 4) return "No such contact";

  if (contacts[index][prop] !== undefined && prop !== "likes") {
    result += contacts[index][prop]
  } else if (contacts[index][prop] !== undefined && prop === "likes") {
    resultArr = contacts[index][prop].splice(0);
    return resultArr
  } else return "No such property"
  
   return `${result}`
};

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

Welcome to the forum @ragNa !

Delete or comment out your console.log() lines, when you check your code. They can mess the tests.
It´s true for every challenge, if you do extra checks, always comment it out or delete it before submitting.

why are you using a template literal here? what if the thing you are retrieving is a number? don’t you think you should return it as a number? same for arrays or other data types

4

Oh yeah, it was just a leftover from previous testing. But yeah it is unneeded there, normally it wasn’t a template literal

5

Yeah, thank you. Removing the console.log that I used to test the code worked. Now it passed all tests.

6

it accidentally pass the tests

call it twice

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

you are changing the contacts object, the second one finds an empty array []

7

damn okay, that makes sense, i’ll keep this information in mind for the future. ty

why don’t you try to write code that does not change the object?
