 In practice, there are mainly two kinds of modules.
 
-1. Module that contains a library, pack of functions, like `say.js` above.
-2. Module that declares a single entity, e.g. a module `user.js` exports only `class User`.

 Mostly, the second approach is preferred, so that every "thing" resides in its own module.
 
-Naturally, that requires a lot of files, as everything wants its own module, but that's not a problem at all. Actually, code navigation becomes easier, if files are well-named and structured into folders.

 Imagine, we're writing a "package": a folder with a lot of modules, with some of the functionality exported outside (tools like NPM allow to publish and distribute such packages), and many modules are just "helpers", for the internal use in other package modules.
