Overview of this book

By learning TypeScript, you can start writing cleaner, more readable code that’s easier to understand and less likely to contain bugs. What’s not to like? It’s certainly an appealing prospect, but learning a new language can be challenging, and it’s not always easy to know where to begin. This book is the perfect place to start. It provides the ideal platform for JavaScript programmers to practice writing eloquent, productive TypeScript code. Unlike many theory-heavy books, The TypeScript Workshop balances clear explanations with opportunities for hands-on practice. You’ll quickly be up and running building functional websites, without having to wade through pages and pages of history and dull, dry fluff. Guided exercises clearly demonstrate how key concepts are used in the real world, and each chapter is rounded off with an activity that challenges you to apply your new knowledge in the context of a realistic scenario. Whether you’re a hobbyist eager to get cracking on your next project, or a professional developer looking to unlock your next promotion, pick up a copy and make a start! Whatever your motivation, by the end of this book, you’ll have the confidence and understanding to make it happen with TypeScript.

Preface

Typing React

Prior to the dramatic rise in the popularity of TypeScript, React programmers either went without any sort of type system or used libraries such as Flow or PropTypes.

Flow is another library developed by Facebook with the intent of adding types to JavaScript. It has similar goals to TypeScript but takes a different route to achieve them. Instead of being a superset of JavaScript, Flow uses comments and type annotations checked by a language server, which are then removed by a transpiler such as Babel. Since both libraries were developed by Facebook, it was common to use them together, but the popularity of Flow has waned as TypeScript has emerged as the type system of choice for web developers.

PropTypes is another library for enforcing type-checking. In this case, the library is specifically for use with React and has the narrow focus of checking types on React "props," or the parameters that are passed along with components.
