学习基础知识：学习 TypeScript 的不同类型和类型运算符，了解其作用和用法。 探讨高级话题：理解 TypeScript 复杂的类型系统，学习如何安全地处理错误和构建异步程序。 联系实际应用：在你钟爱的前后端框架中使用 TypeScript，把现有的 JavaScript 项目迁移到 TypeScript，以及在生产环境中运行 TypeScript 应用。

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.

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)

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。

Over the past 10 years, distributed systems have become more fine-grained. From the large multi-million line long monolithic applications, we are now seeing the benefits of smaller self-contained services. Heavy-weight, hard to change Service Oriented Architectures are not the answer; instead we are now seeing finer-grained systems consisting of collaborating microservices. Eas...(展开全部)
