Exporting files from note.js to use in app.js

For now though, the focus will be to export something from notes.js which we can use in app.js. Inside notes.js (actually, inside all of our Node files), we have access to a variable called module. I'll use console.log to print module to the screen so that we can explore it over in Terminal, as shown here:

console.log('Starting notes.js');

console.log(module);

Let's rerun the file to explore it. As shown in the following screenshot, we get a pretty big object, that is, different properties related to the notes.js file:

Now, to tell the truth, we'll not be using most of these properties. We have things such as id, exports, parent, and filename. The only one property we'll ever use in this book is exports.

The exports object on the module property and everything on this object gets exported. This object gets set as the const variable, notes. This means that we can set properties on it, they will get set on notes, and we can use them inside app.js.
