Why {} != ( {} ) in JavaScript?

Question

It\'s commonly known that {} is shorter way to define an object like [] is for an array.

But now I am wondering why:

{} !=          


        

Answer 1

{} != {} is true because both {}'s are completely different objects. However, variables that are referencing the same object hold equality:

​var a = {},
    b = a;

assert( a == b )​
