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

问题描述

为避免在IF条件下使用NOT运算符以使代码更易读，这是一个很好的做法吗？我听说 if（doSomething（））比更好，如果（！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

这取决于你想要完成的事情。如果你没有else子句那么 if（！doSomething（））似乎没问题。但是，如果你有

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' d可能会反转该逻辑以删除！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.
