Profile Lookup: return value problem

Tell us what’s happening:
I’m getting an error at this part

if(contacts[i].hasOwnProperty == true) {
return contacts[i][prop];
}

But I can’t find what’s wrong here. I looked for solutions, but they had the same code for this part.

Your code so far


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

// Change these values to test your function
lookUpProfile("Akira", "likes");

Hi @Lalit

hasOwnProperty is actually a method that returns a boolean, so you would want to use it like this: contacts[i].hasOwnProperty(prop).

Also, you may want to look over your logic, as it currently stands, you’ll only ever check the first element of the array before returning.

Thanks, it was the logic part.
