About the Technology
TypeScript is an extension of JavaScript that includes key language features such as optional static typing, compile-time error catching, and auto-complete. By specifying types and type annotations, your code becomes much easier to interpret, which improves productivity and team development. In particular, TypeScript makes complex applications like SPAs much easier to maintain and extend. What’s more, you can use TypeScript with any JavaScript library, so you get full access to new features. And since it compiles to clean JavaScript code, you can run TypeScript on all major browsers!About the book
TypeScript Quickly teaches you to build outstanding modern apps with Typescript! To start, you’ll master the TypeScript syntax, preparing you to delve into the practical examples that follow. Thanks to the authors’ easy-to-digest style, you’ll effortlessly learn about types, object-oriented programming with classes and interfaces, and using TypeScript with JavaScript libraries. You’ll discover TypeScript’s excellent tooling as you explore code-quality improvement with TSLint, debugging with source maps, unit testing, and more.
As you progress through this code-centric guide, you’ll dive into advanced features including decorators, namespaces, and dynamic imports. To clinch your new knowledge, you’ll go hands-on as you develop several different blockchain apps, step by step.
