CoffeeScript？

CoffeeScript

 

http://coffeescript.org/

CoffeeScript is a little language that compiles into JavaScript. Underneath all those awkward braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

The golden rule of CoffeeScript is: "It's just JavaScript". The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable and pretty-printed, passes through JavaScript Lint without warnings, will work in every JavaScript runtime, and tends to run as fast or faster than the equivalent handwritten JavaScript.

 

CoffeeScript这一门编程语言构建在JavaScript之上，其被编译成高效的JavaScript，这样你就可以在web浏览器上运行它，或是通过诸如用于服务器端应用的Node.js一类的技术来使用它。编译过程通常都很简单，产生出来的JavaScript与许多的最佳做法都保持了一致。
