To get the most out of this book

All the code examples in this book were tested using Deno 1.7.5 on macOS, but they should work in future releases of Deno. A few third-party packages were also used in the course of the book. The examples using them should also apply to newer versions of the software.

The book will provide installation instructions for all the pieces of software used.

This book's code was written using VS Code (https://code.visualstudio.com/) for the best experience using the official Deno extension. This is not a requirement and the book can be followed using any coding editor.

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.

You should be comfortable using JavaScript and have basic knowledge of TypeScript. Node.js knowledge is not required but might be useful.
