Ultimate Typescript Handbook [EPUB ebook] 
Build, scale and maintain Modern Web Applications with Typescript

DESCRIPTION
This book provides a comprehensive guide to Type Script, a programming language that extends Java Script with powerful features like static typing, classes, and interfaces. The book is divided into thirteen chapters that cover everything from setting up a development environment to building an Angular app with Type Script. 
We start with an introduction to Type Script and its benefits and go on to explain how Type Script can help developers write more maintainable, scalable code and catch errors before they make it to production. The book then dives into more technical topics like basic type annotations, using the Type Script compiler, advanced features like enums and interfaces, and manipulating types. 
The book then discusses chapters on classes and control flow analysis that are particularly helpful for developers looking to build more complex applications. The book teaches by example, with numerous code examples that illustrate the main concepts and approaches towards writing Type Script programs and codes and finishes with a comprehensive practical example that shows step-by-step development of a modern web application using Type Script and Angular.
