In this chapter, we reviewed what is to be expected throughout the rest of this book. We discussed the amazing current state of JavaScript and how it can be used to power the full stack of a web application. Not that you needed any convincing in the first place, but I hope you're excited and ready to get started writing web applications using Node.js and MongoDB!

Next up, we will set up your development environment and get you up and running with Node.js, MongoDB, and npm, as well as write and launch a quick Node.js app that uses MongoDB!
