In this chapter, we have written a multi-environment module following the universal module definition pattern, created an npm package for a library and a command-line tool, and packaged Node.js code for the browser using Browserify.
This demonstrates the flexibility of Node.js and the range of use cases for JavaScript and npm beyond just server-side code. In the final chapter, we'll look at the broader context around Node.js. We'll see some of the newer languages and upcoming language features for the platform and how Node.js interacts with other platforms like .NET.
