Rule Details

The rule should warn against code that tries to compare against -0, since that will not work as intended. That is, code like x === -0 will pass for both +0 and -0. The author probably intended Object.is(x, -0).

该规则对试图与 -0 进行比较的代码发出警告，因为并不会达到预期。也就是说像 x === -0 的代码对于 +0 和 -0 都有效。作者可能想要用 Object.is(x, -0)。
