Cloning Proxy-wrapped objects with _.cloneDeep in Lodash 4.x: expected behavior vs observed outcome
Determine whether Lodash 4.x's _.cloneDeep produces a truly detached copy when the source value includes Proxy‑wrapped objects, functions, DOM nodes, or WeakMap entries. Because the algorithm treats uncloneable values as plain objects and does not invoke Proxy traps, it is unclear whether the resulting clone retains any behavioral link to the original handle
