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.

Angular 1

AngularJs version 1 (or just Angular 1) is a very popular JavaScript framework, and was built and distributed by Google. It has, however, been superseded by Angular 2, which uses TypeScript as its language of choice, which we will cover in the next chapter. This section of the chapter will discuss writing Angular 1 code with TypeScript, as an example of a semi-compatible third-party library.

Angular 1 takes a completely different approach to building JavaScript SPA's, introducing an HTML syntax that the running Angular 1 application understands. This provides the application with two-way data binding capabilities, which automatically synchronizes models, views, and the HTML page. Angular 1 also provides a mechanism for dependency injection (DI), and uses services to provide data to your views and models.

Let's take a look at a sample from the Angular v1.7...
