How does JavaScript's Object.is() work?

Sometimes you see of frameworks like ReactJS uses Object.is(), and how can you think of it?

It really is just the same as === except two cases:

> 0 === -0
true

> Object.is(0, -0)
false

> NaN === NaN
false

> Object.is(NaN, NaN)
true

Object.is() works just like === except these two cases, so next time when you see Object.is(), you can think of it roughly equivalent to === except these two minor details.

This is in fact the comparison method used in ReactJS Hooks, such as useEffect(), where the dependency array elements are compared using Object.is().
