JavaScript nan-The only one who does not equal himself to the object!!

Why is the Nan of JavaScript not equal to Nan

In js object = = = Object Feels like there's nothing wrong with both of these represent one thing

But what if you tried nan = = = Nan is return false?

Because Nan is: not a number is not a numeric abbreviation

Since it's not a number, it's good to understand that ' a ' is not a number, ' B ' is not a number.

So since both of them are not numbers, is ' A ' = = ' B '? Obviously not.

So->nan = = = NaN =>false
