Logic Question from Javascript

Question

Not looking for answer, just explanation.

var a={}, b={}
console.log(a===b)
//Returns false????

Both are same type, same scope, both empty values why are they not the same?

Answer 1

Take a look here:

Answer 2

Aren't those 2 different objects?
Not sure about JavaScript but in Java it would return false because both will have different reference.

Answer 3

nice article honfu,

just to provide further enrichment : the isEquivalent function in the article uses !== to check the values in the objects, this assumed that they will be string, number or boolean; when the object is nested, the values are also object-type, including array, this approach fails. instead, it should check the type of the value, and if the value is object, call isEquivalent itself.
