Your code so far

I know my code is a stupid solution (because I forget to use hasOwnProperty method.) :joy:

but I’m still curious why it can’t work.

Thank you for help. :blush:

// 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) {

  for(let i=0 ; i<contacts.length; i++){
    if(name==contacts[i].firstName){
      if(prop==contacts[i].lastName){
        return contacts[i].lastName;
      }else if(prop==contacts[i].number){
        return contacts[i].number;
      }else if(prop==contacts[i].likes){
        return contacts[i].likes;
      }else{
        return "No such property."}
    }
  }  
return "No such contact."        
}
    
lookUpProfile("Akira", "likes");

Can this ever be true? Will a person’s last name ever be the string ‘lastName’?
