14.6 协程和恢复（recover） 14.7 新旧模型对比：任务和worker 14.8 惰性生成器的实现 14.9 实现 Futures 模式 第 15 章 网络，模板和网页应用 15.1 tcp服务器 15.2 一个简单的网页服务器 15.3 访问并读取页面 15.4 写一个简单的网页应用 第 16章 常见的陷阱与错误 16.1 误用短声明导致变量覆盖 16.2 误用字符串 10 倍，并且能够更加高效地使 用内存。 其实比较多门语言之间的性能是一种非常猥琐的行为，因为任何一种语言都有其所擅长和薄弱的方面。例如在处理文 本方面，那些只处理纯字节的语言显然要比处理 Unicode 这种更为复杂编码的语言要出色的多。有些人可能认为使 用两种不同的语言实现同一个目标能够得出正确的结论，但是很多时候测试者可能对一门语言非常了解而对另一门语 言只是大概明白，测试者对程序编写 代码中的几乎所有东西都有一个名称或标识符。另外，Go 语言也是区分大小写的，这与 C 家族中 的其它语言相同。有效的标识符必须以字符（可以使用任何 UTF-8 编码的字符或 _ ）开头，然后紧跟着 0 个或 多个字符或 Unicode 数字，如：X56、group1、_x23、i、өԑ12。 以下是无效的标识符： 1ab（以数字开头） case（Go 语言的关键字） a+b（运算符是不允许的） _ 本身就是一个
