14.6 Conclusion 结论

Well chosen names help to make code more obvious; when someone encounters the variable for the first time, their first guess about its behavior, made without much thought, will be correct. Choosing good names is an example of the investment mindset discussed in Chapter 3: if you take a little extra time up front to select good names, it will be easier for you to work on the code in the future. In addition, you will be less likely to introduce bugs. Developing a skill for naming is also an investment. When you first decide to stop settling for mediocre names, you may find it frustrating and time-consuming to come up with good names. However, as you get more experience you’ll find that it becomes easier; eventually, you’ll get to the point where it takes almost no extra time to choose good names, so you will get the benefits almost for free.

精心选择的名称有助于使代码更明显。当某人第一次遇到该变量时，他们对行为的第一次猜测是正确的。选择好名字是第 3 章讨论的投资思维方式的一个示例：如果您花一些额外的时间来选择好名字，那么将来您将更容易处理代码。此外，您不太可能引入错误。培养命名技巧也是一项投资。当您第一次决定停止为平庸的名字定居时，您会发现想出好名字的过程既令人沮丧又耗时。但是，随着您获得更多的经验，您会发现它变得更加容易。最终，您将几乎不需要花费额外的时间来选择好名字，因此您几乎可以免费获得好处。
