1. 循序渐进地呈现学习内容，以便于你在不依赖后置知识框架的情况下轻松完成现有的学习任务，同时尽量保证前面章节的内容在后面的学习中得到运用。如果确有必要引入我们还没学习到的知识概念，我会做个简短地介绍。

2. 尽可能地使用简单和简短的示例，方便读者理解。而不强求引入解决实际问题的例子。因为我发现，相比解决某个实际问题，读者更乐于看到自己真正理解了示例的每个细节。或许我会因为这些“玩具示例”而被一些人所诟病，但我更愿意看到我的读者们因此能保持饶有兴趣地学习。

3. 把我知道以及我认为对于你学习语言很重要的东西都告诉你。我认为信息的重要性是分层次结构的。绝大多数情况下，我们没必要弄清问题的所有本质。好比编程语言中的某些特性和实现细节，95% 的程序员都不需要去知道。这些细节除了会加重你的学习成本，还让你更觉得这门语言好复杂。如果你非要考虑这些细节，那么它还会迷惑该代码的阅读者/维护者，所以我主张选择简单的方法解决问题。
