class 1 homework

Wrote two different functions for the homework.  One I did in class and the other I did at home.  The second function was an attempt to make the code shorter.
i think `if !()` would be the same as what is inside the else statement
```
var preferredName1 = function(FirstName,LastName) {
  if (FirstName || LastName) {
    return FirstName || LastName    
  }  else {
    return false;
  }
}
```

would be the equivalent. and i think this isnt quite right because it will return the firstName if both names are supplied. we want it to return false in that case.
