This book is for JavaScript developers seeking to utilize their Node.js and Typescript skills to build microservices and move away from the monolithic architecture. Prior knowledge of TypeScript and Node.js is assumed.

The book introduces the TypeScript language and its features to anyone looking to develop rich web applications. Whether you are new to web development or are an experienced engineer with strong JavaScript skills, this book will get you writing code quickly. A basic understanding of JavaScript and its language features are necessary for this book.

Refactoring improves your code without changing its behavior. With refactoring, the best approach is to apply small targeted changes to a codebase. Instead of doing a huge sweeping change to your code, refactoring is better as a long-term and continuous enterprise. Refactoring TypeScript explains how to spot bugs and remove them from your code.You’ll start by seeing how wordy conditionals, methods, and null checks make code unhealthy and unstable. Whether it is identifying messy nested conditionals or removing unnecessary methods, this book will show various techniques to avoid these pitfalls and write code that is easier to understand, maintain, and test.By the end of the book, you’ll have learned some of the main causes of unhealthy code, tips to identify them and techniques to address them.

微软推出的开源TypeScript语言是JavaScript的超集，引入了静态类型和面向对象的若干特征，可以分模块构建易维护的JavaScript代码。本书用于TypeScript 3.3.3入门，以构建大型可扩展的Web应用。 本书分为10章，介绍TypeScript的基本类型、变量、运算符、数字和字符串，流程控制，数组、元组、迭代器和生成器，函数，常用的几款工具，面向对象编程，泛型，声明文件与项目配置，以及App实战项目等。最后，给出TypeScript JSX的基础内容作为参考。作者还为每章配备了课件与教学视频，方便自学。本书内容详尽、示例丰富，既适合TypeScript初学者及前端开发人员阅读，也适合高等院校和培训学校计算机相关专业的师生教学参考。

Any programmer working with a dynamically typed language will tell you how hard it is to scale to more lines of code and more engineers. That’s why Facebook, Google, and Microsoft invented gradual static type layers for their dynamically typed JavaScript and Python code. This practical book shows you how one such type layer, TypeScript, is unique among them: it makes programmin...(展开全部)
