function print(message) { } ?

I think I need a refresher. :( Is (message) simply a placeholder? I don't see a message variable in the code. If so, does it get updated when the message parameter is replaced and the function is called? Thanks.

:point_right: In a function definition, the parameter names represent the actual arguments that will be provided when the function is called. The name of any parameter is not important, but as a general practice a name is often chosen that reflects what the variable is used for within the function.

Message is a parameter that will be referenced in the code when it is written. As is, it simply is saying the message will be passed to the function and the function will print it out.
