You return from the for loop if the firstName property of the first object in the contacts array does not match name, ie this will only ever work for the value Akira. You need to wait until after the for loop to return with "No such contact".

can you pls tell me the solution

No I can’t, but you can look up the solution on the hints page if you’re ready to give up.

All you need to change is the placement of this line:

return "No such contact"

Right now it’s inside the for loop (before the closing }), it needs to be outside the for loop (after the closing })

Hi, here is my solution to this challenge!
// Only change code below this line

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

It takes me up to four hours to solve this, I shake the world! I shake the world! I shake the world!!!

function lookUpProfile(name, prop){
// Only change code below this line
for(var a = 0; a < contacts.length; a++){
if(contacts[a].firstName === name){
if(contacts[a].hasOwnProperty(prop)){
return contacts[a][prop];
}
return “No such property”;
}
}
return “No such contact”;
// Only change code above this line
}
var x = lookUpProfile(“Kristian”, “lastName”);
console.log(x);
