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.

Summary

In this chapter, we have had a quick look at what TypeScript is and what benefits it can bring to the JavaScript development experience. We also looked at setting up a development environment using some popular IDEs, and had a look at what a bare-bones development environment would look like. Now that we have a development environment set up, we can start looking at the TypeScript language itself in a bit more detail. In the next chapter, we will discuss the basic types that are available within TypeScript, and then discuss the various ways that these types can be used with variables or functions.
