What are the best practices for immutability in programming?

Immutability is a key concept in programming that helps prevent unintended side effects. Best practices include using immutable data structures, avoiding direct mutation of objects, and leveraging libraries that support immutability.

Can you give me an example of an immutable data structure?

Sure! In JavaScript, you can use the Object.freeze() method to create an immutable object. For example: const obj = Object.freeze({ name: 'Alice' }); This prevents any changes to obj.

What are the benefits of using immutability?

The benefits include easier debugging, improved performance in concurrent programming, and enhanced predictability of your code.

Are there any downsides to immutability?

Yes, some downsides include potential performance overhead due to the creation of new objects and increased memory usage. However, the trade-offs often lead to more maintainable code.
