Answer 2

because 'a' is only a reference to an object and 'b' also.
They have the same values (a and b), right, but the object exists 2 times, and both have a different adress in the RAM.
Like you compare if(0xff6384 === 0xaa6384) I would say 🤔
But maybe I'm wrong!

Whats also funny, try to compare [] with [] 😂
if([] == []){
//this will never executed
}

Answer 3

A and b aren't the same object.
Using ==, the output is "a".

Answer 4

Sorry, using ==, it doesn't work...
🤔I will try to give you a correct answer...

Answer 5

thanks a lot ^_^, l was comparing objects:D

Answer 6

The content is equal but the object is different. Use:

(a.valueOf === b.valueOf)
