Object.is

Object.is() is a method for comparing two values with stricter behavior than ===. It handles two edge cases differently: Object.is(NaN, NaN) returns true (while NaN === NaN is false), and Object.is(+0, -0) returns false (while +0 === -0 is true). It is useful when exact value identity is needed.
