1. It works with `NaN`: `Object.is(NaN, NaN) === true`, that's a good thing. 1. It works with `NaN`: `Object.is(NaN, NaN) === true`, that's a good thing.
2. Values `0` and `-0` are different: `Object.is(0, -0) === false`, technically that's true, because internally the number has a sign bit that may be different even if all other bits are zeroes. 2.
