Object.freeze vs Shallow Copy
Developers should use Object meets developers should use shallow copy when they need a quick, memory-efficient duplication of an object where only top-level modifications are required, and shared references to nested data are acceptable or desired. Here's our take.

Nice PickDevelopers should use Object
Pros
- +freeze when they need to enforce immutability for objects, such as in functional programming paradigms, configuration objects, or constants that should not be modified at runtime
- +Related to: javascript, immutability
Cons
- -Specific tradeoffs depend on your use case

The Verdict
Use Object.freeze if: You want freeze when they need to enforce immutability for objects, such as in functional programming paradigms, configuration objects, or constants that should not be modified at runtime and can live with specific tradeoffs depend on your use case.
Use Shallow Copy if: You prioritize it is particularly useful in scenarios like creating snapshots of state in ui frameworks (e over what Object.freeze offers.
