在 IF 条件下使用 NOT 运算符 [英] Using NOT operator in IF conditions

问题描述

避免在 IF 条件下使用 NOT 运算符以提高代码可读性真的是一个好习惯吗?我听说 if (doSomething()) 比 if (!doSomething()).

Is it really a good practice to avoid using NOT operator in IF conditions in order to make your code better readable? I heard the if (doSomething()) is better then if (!doSomething()).

推荐答案

这实际上取决于您要实现的目标.如果您没有 else 子句，那么 if(!doSomething()) 似乎没问题.但是，如果您有

It really depends on what you're trying to accomplish. If you have no else clause then if(!doSomething()) seems fine. However, if you have

if(!doSomething()) {
    ...
}
else {
    // do something else
}

我可能会颠倒这个逻辑以删除 ! 运算符并使 if 子句更加清晰.

I'd probably reverse that logic to remove the ! operator and make the if clause slightly more clear.
