Good code is its own best documentation.
As you’re about to add a comment,
ask yourself, ‘How can I improve the code so that this comment isn’t needed?’
Improve the code and then document it to make it even clearer.
好的代碼自己本身就是最好的文檔。
當你打算加註釋的時候，
問問自己“我如何才能把我的代碼改善到不需增加註釋？
重構自己的代碼，然後使文檔讓其更清楚。
Real programmers don’t comment their code.
If it was hard to write, it should be hard to understand.
真正程序員從來不寫代碼的註釋，
如果代碼非常難寫，那麼同樣代碼的註釋也會非常難懂.
most debugging problems are fixed easily;
identifying the location of the problem is hard.
修復bug很容易，但是定位bug卻很困難
