Extra character counted in completeName.length

This is in reference to https://teamtreehouse.com/library/the-solution-4... Since the variable completeName has an empty string with a space in it, it counts that as a character. So when you run the final program it adds an extra character to the final count of your full name. How can you go about subtracting the additional character count created by the space in the empty string, but still having a space between your first and last name?

Depends on what you are using it for. In some cases counting the space as a character is important. But you could always do this:

var characterCount = firstName.length + lastName.length;

or

var characterCount = completeName.length - 1;
