How do I choose between mutable and immutable data structures?

I'm confused about when to use mutable vs immutable data structures. Can you help me understand?

Sure! Mutable data structures can be changed after creation, while immutable ones cannot. What are you trying to achieve?

I want to optimize performance in my application. Should I lean towards one type?

If performance is key, immutable structures can be beneficial for thread safety and easier debugging, but they may have overhead. Mutable structures are faster for frequent updates.

Are there specific scenarios where one is clearly better than the other?

Yes! Use immutable structures for functional programming or when you need to ensure data integrity. Mutable structures are great for scenarios with frequent changes.
