Explanation

Files should end in a trailing blank line.

This is mostly for historical reasons: every text file should end with a \n, or newline since this acts as eol or the end of the line character.

Most text editors ensure this "final newline" automatically.

Like all Readability issues, this one is not a technical concern. But you can improve the odds of others reading and liking your code by making it easier to follow.
