Tell us what’s happening:

function lookUpProfile(name, prop){

for(var i=0;i<contacts.length;i++)

{

    if(contacts[i].firstName == name && contacts[i].hasOwnProperty==prop)

        {

           return contacts[i][prop];

        }

    if(contacts[i].firstName!=name)

        {return "No such contact";}

    if(contacts[i].hasOwnProperty != prop)

        {return "No such property";}

}

}


**Your code so far**
      
```js

var contacts = [
  {
      "firstName": "Akira",

When i run your code it gives the next error on this line


function lookUpProfile(name, prop){
for(var i=0;i<contacts.length;i++)
{

The error says its already being declared meaning its already in use before

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
