Object Equality in jQuery3+

Object Equality in jQuery3+

Comparing same objects from the two different array  and it return false in jQuery. I can't able to find where it is differ.

To illustrate this, I have fiddle links for these

Sample

Why we have to use the JSON.stringify to compare the object .if an object contain array of object it return circular reference issue. so how could i compare the object in jquery without JSON.stringify.
