Mastering TypeScript 3 - Third Edition

Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Object-Oriented Programming

In 1995, the Gang of Four (GoF) published a book named Design Patterns: Elements of Reusable Object-Oriented Software. In it, the authors, Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, describe a number of classic software design patterns, which present simple and elegant solutions to common software problems. If you have never heard of design patterns, such as a Factory pattern, Composite pattern, Observer pattern, or Singleton pattern, then reading through this GoF book is highly recommended.

The design patterns presented by the GoF have been reproduced in many different programming languages, including Java and C#. Vilic Vane has authored a book named TypeScript Design Patterns, in which each of these GoF patterns is implemented and discussed from a TypeScript perspective.
