//Setup
var contacts = [

        "number": "0543236543",
        "likes": ["Pizza", "Coding", "Brownie Points"]

function lookUpProfile(firstName, prop){
// Only change code below this line
  
 var i=0;
while(i<3){
           
  if (contacts[i]["firstName"]===firstName && contacts[i].hasOwnProperty(prop) ){
      
          return contacts[i][prop];
   }
      else if (contacts[i]["firstName"]!==firstName){
           
           return "No such contact";

   }       
       else if (contacts[i]["firstName"]===firstName && !contacts[i].hasOwnProperty(prop)){
      
          return "No such property";
    }
      
   
      else {
  
           return "Error in coding";    
  }
   i++;
}
// Only change code above this line
}

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

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.
