Learning TypeScript 2.x - Second Edition

By: Remo H. Jansen

Overview of this book

TypeScript is an open source and cross-platform statically typed superset of JavaScript that compiles to plain JavaScript and runs in any browser or host. This book is a step-by-step guide that will take you through the use and benefits of TypeScript with the help of practical examples. You will start off by understanding the basics as well as the new features of TypeScript 2.x. Then, you will learn how to work with functions and asynchronous programming APIs. You will continue by learning how to resolve runtime issues and how to implement TypeScript applications using the Object-oriented programming (OOP) and functional programming (FP) paradigms. Later, you will automate your development workflow with the help of tools such as Webpack. Towards the end of this book, you will delve into some real-world scenarios by implementing some full-stack TypeScript applications with Node.js, React and Angular as well as how to optimize and test them. Finally, you will be introduced to the internal APIs of the TypeScript compiler, and you will learn how to create custom code analysis tools.

Visual Studio Code

Visual Studio is a lightweight but powerful code editor with an extensive number of features. Learning all these features is out of the scope of this book because we could dedicate an entire book to cover them. However, we are going to dedicate a little bit of time to learning about two of the best features available in this code editor: quick fixes and the code debugger.

It is recommended to read the Visual Studio Code user guide at https://code.visualstudio.com/docs/editor/codebasics to learn how to make the most of this IDE.

Quick fixes

Visual Studio Code can detect some errors and automatically fix them using a set of features known as quick fixes.
