**Tell us what’s happening:**

I don’t get is it correct expected output

" `bob.getFullName()`

should return “Haskell Curry” after `bob.setLastName("Curry")`

."

It is the only criteria in this task which i can’t pass and i don’t understand why getFullName should has first and last name changed if we set only last name

**Your code so far**

```
var Person = function(first,Last) {
// Complete the method below and implement the others similarly
this.getFullName = function() {
return first + " " + Last;
}
this.getFirstName = function() {
return first;
}
this.getLastName = function() {
return Last;
}
this.setFirstName = function(input) {
first = input;
}
this.setLastName = function(input) {
Last = input;
}
this.setFullName = function(input) {
let lt = input.split(" ");
first = lt[0];
Last = lt[1];
}
};
var bob = new Person('Bob','Ross');
bob.setLastName("Curry")
console.log(bob.getFullName());
```
