Because of this, javascript has a +0 and a -0. They make a fun trivia question because there are very few ways to distinguish them since most of the ways of checking equality (even ===) will report that they are equal. In fact, I only know two ways to distinguish them: divide something by them, and you get positive infinity for +0 and negative infinity for -0, or you can use Object.is(-0, 0) which will return false.
