Scope in javascript acting weird

Question

Object are passed with their reference in javascript. Meaning change in that object from any where should be reflected. In this case, the expected output was {} for console.log(

Answer 1

Okay, so you've figured out that JavaScript objects have reference semantics, so modifying a referent has an effect on the same object in the original scope.

What you also need to realise is that = is not part of these rules; not only does it perform assignment, but it will also rebind the reference to a new object.

Under the hood, so to speak, that's basically how your original references were formed.
