TypeScript in 50 Lessons

Book Description

Every other day, one of your team members makes a case for switching from “chaotic” JavaScript to “sane” TypeScript. Maybe you rely on not-very-well-understood JavaScript libraries, or you have a large number of contributors, or the code base is difficult to maintain. The reasons are always similar, but so is the hesitance from the team. Why change the stack that seems to be working just fine?

That’s the question we’ve asked ourselves as well. So we’ve teamed up with Stefan Baumgartner, a seasoned JavaScript developer drawn to TypeScript for years, to break it all down into understandable pieces. The result is TypeScript in 50 Lessons — our shiny new book, with everything TypeScript explained, from start to finish.

WHO IS THIS BOOK FOR?

It’s for developers who know enough JavaScript to be dangerous. If you are spending an increasing amount of time programming and want to be more productive, that’s the book you. With TypeScript, you can get more out of your JavaScript code – for yourself and your colleagues.

The book is also for developers who dipped their toes into TypeScript and now want to get their feet wet. If you want to learn about type systems and how they can be used to define complex JavaScript scenarios, this book will help you, too. This knowledge will ultimately become language-independent, preparing you for different programming languages that have elaborate type systems.

If you ever find yourself:

• writing JavaScript with libraries and frameworks you barely know
• writing JavaScript with other developers
• writing JavaScript that deals with back-end data
• writing JavaScript that your future self has to continue working on

…then TypeScript will do right by you.

书名：50课打字稿

每隔一天，您的一个团队成员就会提出一个理由，要求从“混乱”的脚本转换为“正常”的打字脚本。可能您依赖的是不太容易理解的JavaScript库，或者您有大量的贡献者，或者代码库很难维护。原因总是相似的，但球队的犹豫也是如此。为什么要更改似乎运行良好的堆栈？

这也是我们一直在问自己的问题。因此，我们与Stefan Baumgartner合作，将其分解为易于理解的部分。Stefan Baumgartner是一名经验丰富的JavaScript开发人员，多年来一直致力于打字。结果是50节课的打字稿–我们闪亮的新书，从头到尾都有打字稿的解释。

这本书是给谁看的？

这是给你的。了解足够多的Java脚本的开发人员是危险的。如果你花在编程上的时间越来越多，并且想要更有效率，这本书就是你。使用TypeScrip，您可以为您自己和您的同事从您的Java代码中获得更多。

这本书也是为我们准备的。涉足打字工作的开发人员现在，他们想把脚弄湿。如果您想了解类型系统以及如何使用它们来定义复杂的JavaScript场景，这本书也会对您有所帮助。这些知识最终将独立于语言，使您为使用具有复杂类型系统的不同编程语言做好准备。

如果你发现自己：

• 使用您几乎不了解的库和框架编写JavaScript
• 与其他开发人员一起编写Java脚本
• 编写处理后端数据的Java脚本
• 编写你未来的自己必须继续努力的Java脚本

那么打字稿会对你有好处的。
