P12 - 🚀 Deep vs Shallow Copy – The Ultimate Guide! 🔥 | JSON, Clone, Manual Recursion
Next Vidoe link - • P13 -🚀 Deep Copy – The Ultimate Guide! 🔥 |...
📌 Key Takeaways:
✅ Shallow vs Deep Copy: Shallow copy shares references, deep copy does not.
✅ JSON Serialization (JSON.stringify & JSON.parse) – Simple but loses functions, undefined, Symbol, and complex structures.
✅ structuredClone() – The best native way to deep copy, but not available in all environments (Node.js needs polyfill).
✅ Manual Recursive Deep Copy – Custom logic to handle nested structures but requires extra handling for circular references.
✅ lodash.cloneDeep() – Most reliable for all cases (Date, Set, Map, circular references).
✅ Performance Matters! Using deep copies incorrectly can impact app efficiency.
