TypeScript Revealed

Book Description

TypeScript Revealed is a quick 100-page guide to Anders Hejlsberg’s new take on JavaScript. With this brief, fast-paced introduction to TypeScript, .NET, Web and Windows 8 application developers who are already familiar with JavaScript will easily get up to speed with TypeScript and decide whether or not to start incorporating it into their own development.

TypeScript is ‘JavaScript for Application-scale development’; a superset of JavaScript that brings to it an additional object-oriented-like syntax familiar to .NET programmers that compiles down into simple, clean JavaScript that any browser can run today. It’s also tied to the next version of the JavaScript standard, which means that TypeScript will continue to evolve over time to keep in step with that standard and with the capabilities of the engines that will execute JavaScript applications.

If you are a .NET developer, Web designer or developer, or a programmer with a keen interest in scalable applications, TypeScript Revealed is a great way to get started with the language, learn how it compiles into JavaScript, and how easy it is to learn from a .NET/Java developer’s perspective.

• Takes you through the language features in Typescript additional to those in JavaScript
• Describes the tooling and community support for TypeScript development
• Discusses how TypeScript can be included in ASP.NET, Windows 8, and node.js application development projects.

What you’ll learn

• Why you should care about TypeScript
• What it does and what it doesn’t do
• The current toolset and levels of support
• The new syntax features of TypeScript
• How to build your own TypeScript declaration files
• How to incorporate TypeScript into your projects

Who this book is for

TypeScript Revealed is aimed at the early adopter developer who is already familiar with Microsoft tools and .NET and/or JavaScript development that wants a flavor of TypeScript distilled, culled, and organized in one place.

打字稿揭晓这是一份长达100页的快速指南，介绍了Anders Hejlsberg对JavaScript的新见解。通过这篇简短、快节奏的TypeScrip介绍，已经熟悉Typescrip的.NET、Web和Windows 8应用程序开发人员将轻松掌握TypeScrip，并决定是否开始将其整合到自己的开发中。

TypeScrip是“用于应用程序规模开发的Java脚本”；它是一个Java脚本的超集，为它带来了.NET程序员熟悉的额外的面向对象的语法，它可以编译成简单、干净的Java脚本，现在任何浏览器都可以运行。它还与下一版本的JavaScript标准捆绑在一起，这意味着Type脚本将随着时间的推移继续发展，以与该标准保持一致，并与将执行JavaScript应用程序的引擎的功能保持一致。

如果您是.NET开发人员、Web设计人员或开发人员，或者对可伸缩应用程序有着浓厚兴趣的程序员， 打字稿揭晓 是开始使用该语言的一个很好的方法，了解它如何编译成JavaScript，以及从.NET/Java开发人员的角度学习它是多么容易。

• 带您了解在TypeScrip中的语言功能以及在JavaScript中的语言功能
• 描述用于打字脚本开发的工具和社区支持
• 讨论如何在ASP.NET、Windows 8和node.js应用程序开发项目中包含TypeScrip。

你会学到什么

• Why you should care about TypeScript
• 它做了什么，不做了什么
• 当前的工具集和支持级别
• The new syntax features of TypeScript
• How to build your own TypeScript declaration files
• 如何将打字稿整合到你的项目中
