A Smarter Way to Deep Clone in React: Introducing useDeepClone

Short summary

react-hook-lab introduces useDeepClone, a React hook and standalone deepClone utility that handles circular references, preserves modern JS types (Map, Set, Date, TypedArrays), and maintains reference stability via an internal cache to avoid unnecessary re-renders. The hook skips cloning when the input reference hasn't changed between renders. The post includes code examples for both the utility and hook usage.

• •useDeepClone preserves Map, Set, Date, circular refs, and prototype chains
• •Internal cache skips cloning when input reference is unchanged between renders
• •Standalone deepClone utility available for non-component use cases
