 ## 目标
 
-建立一个 lesson7 项目，在其中编写代码。
+建立一个 lesson7 项目，在其中编写代码，我们暂时命名为 *vendor*
+根据下面的步骤，最终的项目结构应该长[这样](https://github.com/alsotang/node-lessons/tree/master/lesson7/vendor)
 
-main.js: 类似上文提到的 fibonacci 函数。
+这次我们测试的对象是上文提到的 fibonacci 函数
 
 此函数的定义为 `int fibonacci(int n)`
 
 * 当 n === 0 时，返回 0；n === 1时，返回 1;
 * n > 1 时，返回 `fibonacci(n) === fibonacci(n-1) + fibonacci(n-2)`，如 `fibonacci(10) === 55`;

+上面这个代码块会打印五个 `5` 出来，而我们预想的结果是打印 0 1 2 3 4。
 
 之所以会这样，是因为 setTimeout 中的 i 是对外层 i 的引用。当 setTimeout 的代码被解释的时候，运行时只是记录了 i 的引用，而不是值。而当 setTimeout 被触发时，五个 setTimeout 中的 i 同时被取值，由于它们都指向了外层的同一个 i，而那个 i 的值在迭代完成时为 5，所以打印了五次 `5`。

 ## 课程内容
 
+*注意，cnodejs.org 网站有并发连接数的限制，所以当请求发送太快的时候会导致返回值为空或报错。建议一次抓取3个主题即可。文中的40只是为了方便讲解*
+
 这一章我们来到了 Node.js 最牛逼的地方——异步并发的内容了。
 
 上一课我们介绍了如何使用 superagent 和 cheerio 来取主页内容，那只需要发起一次 http get 请求就能办到。但这次，我们需要取出每个主题的第一条评论，这就要求我们对每个主题的链接发起请求，并用 cheerio 去取出其中的第一条评论。

 为什么说 supertest 是 superagent 的孪生库呢，因为他们的 API 是一模一样的。superagent 是用来抓取页面用的，而 supertest，是专门用来配合 express （准确来说是所有兼容 connect 的 web 框架）进行集成测试的。
 
-将使你有一个 app: `var app = express();`，想对它的 get 啊，post 接口啊之类的进行测试，那么只要把它传给 supertest：`var request = require('supertest')(app)`。之后调用 `requset.get('/path')` 时，就可以对 app 的 path 路径进行访问了。它的 API 参照 superagent 的来就好了：http://visionmedia.github.io/superagent/ 。

 Connect中规定`function(err, req, res, next) {}`形式为错误处理函数，`function(req, res, next) {}`为正常的业务逻辑处理函数。那么，可以根据Function.length以判断它是否为错误处理函数。

+本书写成于 2015 年，其中的某些最佳实践或许已经发生变化。比如异步处理应更多使用 `Promise` 与 `await/async`，但本书未有提及。由于 js 一直向后兼容，所以本书中的内容仍然可以正常在生产环境中使用。
