To get the most out of this book
Previous coding experience will help, but is definitely not required. If you have a computer with a text editor (such as Notepad or TextEdit, not Word!) and a browser, you can get started with this book. We encourage you to engage with the exercises and projects, and experiment continually while you go through the chapters, to ensure you are comfortable with each concept before moving on.
