Love to see that my exact solution is the top voted one. :)

I didn't at once guess to combine single and double quotation marks.

I think this is the best practice instead of using map() function that was used above

This is beautiful

Clever

I guess i do. Maybe after I¨ll actually programm something real it might get better.. Still thank you and have nice day. :)

The description doesn't say it.

What will happen if someone has a two part name, like von Braun? Or it will include some tags, processed afterwards, that should be not capitalized?

You're overthinging it :)

I guess. Still better behaviour would be to capitalize every words inside the answer, don't you thing?

How exactly it matters? say_hello('john') => "Hello, john" would be an expected behavior.
