Node is a JavaScript runtime, which means that it is an environment on top of which you can execute your JavaScript code. It is recommended that you make a new folder for all project files that we will use throughout this book.
Managing all the project files can be done with either of these ways:
- Using your favorite text editor application on the Raspberry Pi (if you are using the Raspberry Pi's desktop)
- Using one of the Terminal editors, such as vi or nano. This can be done on SSH or through the Raspberry Pi Terminal application.
- Editing files on a repository on your own computer and pushing changes to the Pi using a version control management tool like Git.
The last method is the most efficient and also the least error-prone. In fact, I feel it's appropriate to take a brief diversion to set it up so that we can work with a much clearer...
