- You can learn how to write code that is typical of TypeScript TypeScript is an open source programming language that adds static typing functionality to JavaScript. This book explains the core JavaScript specifications and functions, as well as TypeScript's unique specifications and functions. You can learn the basic knowledge of TypeScript with just one book. There are many statically typed languages in the world, but TypeScript's type system has unparalleled expressiveness. In order for readers of this book to understand the effectiveness of types and be able to write code that is typical of TypeScript, this book covers everything from basic ways to handle types that increase program safety to the source of TypeScript's high expressiveness. We will cover a wide range of topics, including how to handle the literal, union, and keyof types. In addition, we will explain the best way to handle difficult-to-understand functions and dangerous functions that threaten mold safety, taking into account historical circumstances, purpose, and purpose. Each chapter has a skill test question, so you can proceed with your study while checking your level of understanding.
