To get the most out of this book
It's expected that you have some prior knowledge of JavaScript or other programming languages. In addition, you should be familiar with how to use a Terminal or shell, and how to use a code editor such as Visual Studio Code:
Any chapters or recipes that require special software should cover the installation steps in the Technical requirements or Getting ready sections.
Many of the Terminal steps assume you're operating in a Unix environment. On Windows, you should be able to use the Windows Subsystem for Linux (WSL 2) to complete these steps.
The recipe steps have been tested with a recent version of Node.js 14 on macOS Mojave.
If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
