How do immutable types work?

Can you explain what immutable types are in programming?

Sure! Immutable types are data types whose state cannot be modified after they are created. This means once you create an instance of an immutable type, you cannot change its value.

What are some examples of immutable types?

Common examples include strings, tuples in Python, and the 'final' keyword in Java, which makes a variable immutable.

Why would I want to use immutable types?

Using immutable types can lead to safer code, easier debugging, and better performance in concurrent programming since they can't be changed unexpectedly.

Are there any downsides to using immutable types?

Yes, one downside is that they can lead to increased memory usage since a new instance is created for every change, rather than modifying the existing one.
