What is the performance difference between mutable and immutable data structures?

What is the performance difference between mutable and immutable data structures?

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

Can you give me an example of when to use mutable vs immutable?

Sure! Use mutable structures for frequent updates, like a list of items. Use immutable for fixed data, like configuration settings.

How does this affect memory usage?

Mutable structures can reuse memory, while immutable ones may create copies, leading to higher memory usage.

Are there any performance benchmarks comparing the two?

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