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.

It is popular with development teams that are building web-enabled desktop replacements, as its look and feel is comparable to normal desktop applications. ExtJS, by default, ensures that each application or component will look and feel exactly the same, no matter which browser it is run in, and it requires little or no need for CSS or HTML.

The ExtJS team, however, has not released an official TypeScript declaration file for ExtJS, despite much community pressure. Thankfully, the wider TypeScript community has come to the rescue, beginning...
