thanks this worked for me Finally
function lookUpProfile(name, prop){
// Only change code below this line
for (var i = 0;i < contacts.length; i++){
// nested if statement
if ( name == contacts[i].firstName){
if(contacts[i].hasOwnProperty(prop)===true){
return contacts[i][prop];
}else if (contacts[i].hasOwnProperty(prop)===false){
return "No such property";
}
}
// end of nested if statement
} // end of for loop
return "No such contact";
// Only change code above this line
} // end of lookupprofile function
// Change these values to test your function
lookUpProfile("Akira", "likes");
