In this section, we will use yargs, a third-party npm module, to make the process of parsing much easier. It will let us access things such as title and body information without needing to write a manual parser. This is a great example of when you should look for an npm module. If we don't use a module, it would be more productive for our Node application to use a third-party module that has been tested and thoroughly vetted.
To get started, we'll install the module, then we'll add it into the project, parsing for things such as a title of the body, and we'll call all the functions that will get defined over in notes.js. If the command is add, we'll call add note, so on.
