Unlike in a web browser, every JavaScript file gets its own scope in node. That
means you cannot access its contents from other files, unless you export them.
If you want to access a, b, c from your own file, you have to export them. More
likely, if a, b, c are only used by those 100 functions and are not meant to be
used by your own code, then you don't need to export them.
