Lies the `===` operator tell. JS👽

=== ( “strict equality” ) operator has some nuances. The === operator is designed to lie in two cases of special values: NaN and -0.

Consider:

NaN === NaN;                //false
0 === -0                             //true

You could use 0 === -0 intentionally in your program for whatever reason. ( I know you lot are weird )

✨How to avoid deez pitfalls:

1. Use Number.isNaN(..) for NaN checks.
2. Use Object.is(..) for -0 comparisons (and for NaN too).

Object.is(..) in action:

console.log(Object.is('1', 1));
// Expected output: false

console.log(Object.is(NaN, NaN));
// Expected output: true

console.log(Object.is(-0, 0));
// Expected output: false

const obj = {};
console.log(Object.is(obj, {}));
// Expected output: false

Think of Object.is(..) as the “quadruple-equals” ====, the really-really-strict comparison!😉
