What are the best practices for using mutable objects in programming?

When using mutable objects, it's important to ensure that you manage state changes carefully. Here are some best practices: 1. Limit the scope of mutability. 2. Use immutability where possible. 3. Be cautious with shared references. 4. Document changes clearly.

Can you explain why immutability is preferred in some cases?

Immutability is preferred because it helps prevent unintended side effects, makes code easier to reason about, and can improve performance in concurrent programming by avoiding issues with shared state.

What are some common pitfalls when working with mutable objects?

Common pitfalls include accidental modifications, unexpected side effects, and difficulties in debugging due to shared state. It's crucial to be aware of how and where objects are modified.

How can I effectively manage state in a large application?

To manage state effectively, consider using state management libraries, adopting a clear architecture (like MVC or Flux), and keeping your state as immutable as possible to reduce complexity.
