About this ebook

TypeScript has conquered the world of JavaScript. Identified in developer surveys as one of the world's fastest growing and most popular languages, TypeScript is widely used in consumer and business companies across the world and is frequently credited for helping massive web applications scale. But what exactly is TypeScript? How and why does it work, and how can we use it?

This practical book takes beginner and advanced JavaScript programmers alike from knowing nothing about "types" or "type systems" to full mastery of TypeScript fundamentals.

You'll learn:

  • Benefits of TypeScript and general characteristics of its type system
  • Why and how TypeScript is useful on top of "vanilla" JavaScript
  • How to inform your type system by using development-only type annotations
  • How TypeScript analyzes and understands code to help you augment your existing development patterns
  • How TypeScript helps you work with arrays, classes, functions, objects, and other important built-in JavaScript constructs
  • How to effectively use the plethora of TypeScript configuration options to tailor the TypeScript compiler to your teams and projects
  • A variety of IDE integrations such as automated refactors and intelligent code searches provided by TypeScript to help you develop quickly with fewer bugs

Great book. Wonderful author. Hands down the best explanation of TypeScript I've ever seen. If I had to live on a desert island and could only bring three books, I'd bring two copies of this book and one blank book of equal size with a pen so I could transcribe it into a third.
