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.

As mentioned at the start of this chapter, Angular 2 was a complete rewrite of Angular 1, and used TypeScript as its language of choice. The adopted naming convention from the Angular team is that Angular 1 is now called AngularJs, and Angular version 2 and upward is named Angular. Since the release of Angular 2, the Angular team has released several major updates, and the current version of Angular, at the time of writing, stands at Angular 7. The samples in this book are all using Angular 7, so wherever you see the word Angular, remember that it refers to Angular version 7. In this section of the chapter, we will take a look at how the Model View Controller design pattern is used within Angular.
