[出错的版本](https://studygolang.gitbook.io/learn-go-with-tests/go-ji-chu/maps#shou-xian-bian-xie-ce-shi-4) [原文](https://github.com/studygolang/learn-go-with-tests/blob/master/maps.md#write-the-test-first-4) 原文中在`Update`方法实现处是与刚实现的`Add`方法比较的，翻译中误写成`Create`方法了，实际上没有`Create`方法。

[翻译的concurrence章节](https://github.com/studygolang/learn-go-with-tests/blob/master/zh-CN/concurrency.md#%E5%B9%B6%E5%8F%91)中开头的测试代码用的是最初的代码(仓库中没有记录) [原文对应章节](https://github.com/studygolang/learn-go-with-tests/blob/master/concurrency.md#concurrency)已改成[v3版](https://github.com/quii/learn-go-with-tests/blob/master/concurrency/v3/check_websites_test.go)的代码
