How This Book Is Structured
This book is divided into two parts. Part 1 covers the basics of object-oriented JavaScript. The chapters are intended to be read sequentially. Each chapter builds on the one before it and assumes that you have read all preceding chapters. It is a good idea to read these chapters all the way through because the chapters in Part 2 use the techniques described in Part 1, in some cases without further explanations.
Part 2 covers specific design patterns and their practical applications in JavaScript. Each chapter can be read in whatever order you like. Some chapters reference other chapters, either in Part 1 or Part 2, but we always give the chapter number where more information can be found.
