What are the performance differences between mutable and immutable collections?

What are the performance differences between mutable and immutable collections?

Mutable collections can be changed after creation, while immutable collections cannot. This affects performance in various ways.

Can you give me examples of when to use each type?

Use mutable collections when you need to frequently modify data, like in a dynamic list. Use immutable collections for fixed data, which can improve performance and safety.

How does immutability affect memory usage?

Immutability can lead to higher memory usage due to the creation of new objects for each change, but it can also reduce memory leaks.

Are there any performance benchmarks comparing them?

Yes, benchmarks often show that mutable collections perform better for frequent updates, while immutable collections excel in read-heavy scenarios.
