15.4 Early comments are fun comments 早期注释很有趣

The third and final benefit of writing comments early is that it makes comment-writing more fun. For me, one of the most enjoyable parts of programming is the early design phase for a new class, where I’m fleshing out the abstractions and structure for the class. Most of my comments are written during this phase, and the comments are how I record and test the quality of my design decisions. I’m looking for the design that can be expressed completely and clearly in the fewest words. The simpler the comments, the better I feel about my design, so finding simple comments is a source of pride. If you are programming strategically, where your main goal is a great design rather than just writing code that works, then writing comments should be fun, since that’s how you identify the best designs.

尽早编写注释的第三个也是最后一个好处是，它使编写注释更加有趣。对我来说，编程中最有趣的部分之一是新类的早期设计阶段，在那里，我将充实该类的抽象和结构。我的大部分注释都是在此阶段编写的，这些注释是我记录和测试设计决策质量的方式。我正在寻找可以用最少的词来完整而清晰地表达的设计。注释越简单，我对设计的感觉就越好，因此找到简单的注释是一种自豪感。如果您是策略性编程，而您的主要目标是一个出色的设计，而不仅仅是编写有效的代码，那么编写注释应该很有趣，因为这是您确定最佳设计的方式。
