此书是 [《TypeScript Deep Dive》](https://github.com/basarat/typescript-book/) 的中文翻译版，感谢作者 [Basarat](https://github.com/basarat) 的付出。

如果你喜欢纸质书籍，可以通过[京东](https://item.jd.com/12755624.html)或者[当当](http://product.m.dangdang.com/28487648.html?t=1574581821)，来购买此书。

你可以通过订阅该[公众号](https://cdn.jkchao.cn/nuxt/img/14958af.jpg)，来获取更多有趣的内容。

## Why

如你所见，TypeScript 发展至今，已经成为大型项目的标配，其提供的静态类型系统，大大增强了代码的可读性以及可维护性；同时，它提供最新和不断发展的 JavaScript 特性，能让我们建立更健壮的组件。

[《TypeScript Deep Dive》](https://github.com/basarat/typescript-book/) 是一本很好的开源书，从基础到深入，很全面的阐述了 TypeScript 的各种魔法，不管你是新手，还是老鸟，它都将适应你。此外，它不同于 TypeScript 官方给出的文档（当然 TypeScript 给出的文档是很好的），在此书中，结合实际应用下的场景用例，你将能更深入的理解 TypeScript。

如今社区已经存在部分翻译，但都似乎已经停止更新。

于是在某天的某个冲动之下，这个 RP 就诞生了。

## 翻译内容

《TypeScript Deep Dive》 书中包含一部分 JavaScript Future 和一些其他的内容，在这里，我们并不打算翻译它，如果你有兴趣，可以查看原书中 [JavaScript Future](https://basarat.gitbooks.io/typescript/content/docs/future-javascript.html) 的有关章节。

由于 TypeScript 更新频繁，除了上文中提到翻译部分，将会加入 TypeScript 的 Release，同时我也将总结出工作中一些有意思的点，希望和大家相互学习，一起进步。

此外，在不违背原作者本意前提下，为了更直观的表达，部分内容将采用意译，而非直译。
