Implemented in https://bugs.webkit.org/show_bug.cgi?id=143865.

It is basically the same thing as ===, except Object.is(NaN, NaN) returns true.

I think I still prefer === unless NaN is in the picture. I have a feeling Object.is() would be slower than ===.
Comment 3 Jordan Harband 2015-04-22 12:09:43 PDT 
That's great incentive to make Object.is just as optimized :-) The JIT should be able to inline `Object.is(a, b)` with `a === b || (a !== a && b !== b)` at some point, I'd guess?
