Deep Clone Object

Background

Deep cloning prevents unintended mutations when working with nested data structures in state management.

Problem

Write a function that creates a deep copy of an object or array, ensuring no references are shared between the original and the clone.

Input

A plain object, array, or primitive value that may contain nested structures.

Output

A deep copy with no shared references to the original.

Sample tests

Input: {a: {b: {c: 1}}}

Expected: {a: {b: {c: 1}}} (no shared refs)

Your solution

Learning objective

Understand shallow vs deep copying and recursive object traversal.
