Preface
This book is about learning modern TypeScript design patterns and best practices to prevent common software problems and defects that emerge from complex or difficult-to-understand code. Utilizing design patterns in apps also helps to create relevant abstractions for future maintainers.
This book offers complete step-by-step explanations of essential concepts, practical examples, and self-assessment questions to explore the key design patterns and best practices of modern TypeScript applications.
You'll start by learning about the practical aspects of TypeScript 4 and its new features.
You will then learn about the traditional GOF design patterns, such as behavioral, creational, and structural, in their classic and alternative forms, and we will explain how you can implement them in practice.
You will then enhance your learning of patterns with their Functional Programming (FP) and reactive programming counterparts, coupled together to write better and more idiomatic TypeScript code.
By the end of the book, you will be able to efficiently recognize when and how to use the right design patterns in any practical use cases and be comfortable working on scalable and maintainable TypeScript projects of any size.
