Issue with Variable Declaration and Reference Errors in Node.js REPL and Browser Console

Subsystem

REPL

What steps will reproduce the bug?

In both the Node.js REPL and the browser console, there is a reference error when trying to assign a variable obj1 that has not been declared to another variable obj2 (this is expected).

In the Node.js REPL, after the initial ReferenceError, attempting to correct the code by assigning obj to obj2 results in a SyntaxError due to obj2 being declared already. Further attempts to access obj2 result in a ReferenceError (different from browser).

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

The expected behavior in both the Node.js REPL and the browser console should be consistent with JavaScript's rules for variable declarations and assignments.

What do you see instead?

The obj2 reference error.

FWIW if I recall, there is an open issue about this behavior, but I need to find it.
