Hi there! There is no specific point to using the "#" character here that I'm aware of other than they are checking your ability to be able to do it. You will find that some challenges are like this. They are more about being able to produce the end result per specifications than producing something terribly useful. Remember, most challenges only need a small code snippet to pass them.

This was a way for them to test your ability to make new variables, use the built-in function toUpperCase(), and concatenate effectively.

Hope this helps! :sparkles:
