问题描述
我总是写我的布尔前pressions是这样的：
I have always written my boolean expressions like this:
if (!isValid) {
// code
}
但我的新雇主坚持以下样式：
But my new employer insists on the following style:
if (false == isValid) {
// code
}
是一种风格preferred，或标准？
Is one style preferred, or standard?
推荐答案
我preFER的第一个样式，因为它更自然，我读。这是非常不寻常的看到第二个样式。
I prefer the first style because it is more natural for me to read. It's very unusual to see the second style.
原因之一，有些人会在另一个替代preFER第二：
One reason why some people might prefer the second over another alternative:
if (isValid == false) { ... }
是与后者不小心写一个 = ，而不是 == ，那么你要分配给isValid而不是测试它但与不断首先你会得到一个编译错误。
is that with the latter you accidentally write a single = instead of == then you are assigning to isValid instead of testing it but with the constant first you will get a compile error.
但随着你的第一个建议，这个问题甚至不是一个问题，所以这是另一个原因preFER第一。
But with your first suggestion this issue isn't even a problem, so this is another reason to prefer the first.
