yargs

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.
