/**
 * Allows extraction of a minified key. Let's the build system minify keys
 * without loosing the ability to dynamically use key strings as values
 * themselves. Pass in an object with a single key/val pair and it will return
 * you the string key of that single record. Suppose you want to grab the
 * value for a key 'className' inside of an object. Key/val minification may
 * have aliased that key to be 'xa12'. keyOf({className: null}) will return
 * 'xa12' in that case. Resolve keys you want to use once at startup time, then
 * reuse those resolutions.

【成都社区活动】 NodeSchool Workshop 六月七号（周六）

NodeJS 是现在最热门的 JavaScript 后端框架。你对 NodeJS 有兴趣但一直没机会深度接触吗？

• 你是前端或者移动端开发，想学写简单的后台服务
• 你是后台开发，想尝试用异步框架写高并发服务
• 你是学生，想学些学校没教的新技术，想认识社区的一些牛人

hayeah

暖身周 （可选）

• 写一个简单的 NPM package
• 用 mocha 写测试
• 用 CoffeeScript 写 NPM package
• 实现 JS 类 （练习原型链）

第一周 - Connect Middleware
