Profile Lookup can not pass

Hello ! My can not pass challenge https://learn.freecodecamp.org/javascript-algorithms-and-data-structures/basic-javascript/profile-lookup/
What is wrong with my code

//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
var ar = "";
for (var i = 0; i< contacts.length ; i++) {
if (contacts[i]["firstName"] == name && contacts[i][prop] ) {
    console.log(contacts[i][prop]);
     ar = contacts[i][prop] ;

} else if (contacts[i]["firstName"] !== name   ) {
    ar = "No such contact" ;
     console.log(ar); 
} else  {
    ar = "No such property";
    console.log(ar);
    }
}
return ar ;
// Only change code above this line
}

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

"Kristian", "lastName" should return "Vos"

"Sherlock", "likes" should return ["Intriguing Cases", "Violin"]

"Harry","likes" should return an array

Passed

"Bob", "number" should return “No such contact”

Passed

"Bob", "potato" should return “No such contact”

"Akira", "address" should return “No such property”

How optimized my code from quiz

Hey @Quintis, it looks like you’re proceeding with your loop even after you’ve got firstName match, so your ar variable gets reassigned :slight_smile:

#3

and how to fix it?) What I must to change in my code ?

#4

You can use break to stop a loop, but careful on where you put it

#5

you mean switch case break operators ?

#7

I have made it))))) but how optimize my code ?

//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"]
    },

// Only change code below this line
var ar = "";

if (contacts[i]["firstName"] == name && contacts[i][prop] ) {
    console.log(contacts[i][prop]);
     ar = contacts[i][prop] ;
break
} else if (contacts[i]["firstName"] !== name   ) {
    ar = "No such contact" ;
     console.log(ar); 
    
}
 else  {
    ar = "No such property";
    console.log(ar);
    break;
    }
}
return ar ;
// Only change code above this line

// Change these values to test your function
lookUpProfile("Bob", "number");

Imagine that each object in your array is a paper card and array itself is a stack of these cards laying on the table in front of you? How would you solve it? I personally would find a card with given firstName and then I have 3 options:

  1. If no such card: "No such contact"
  2. If no property on the card: "No such property"
  3. Read the value of the given property

Now, if it sounds like a good plan to you, try to implement it in the code (using Array.prototype.find())

Thank you)

What is the link to the challenge, what errors are you getting / what are you not passing. What does the console log.

I have no errors, just want to see how optimized my code
