What are immutable parameters and why are they important?

Immutable parameters are values that cannot be changed after they are created. They are important because they help prevent unintended side effects in functions, making code easier to understand and maintain.

Can you give me an example of how immutable parameters work?

Sure! In a function that takes an immutable parameter, if you try to modify it, you'll get an error. This ensures that the original value remains unchanged.

What are the benefits of using immutable parameters in programming?

The benefits include improved code reliability, easier debugging, and enhanced performance in concurrent programming, as immutable objects can be shared safely.

Are there any downsides to using immutable parameters?

One downside is that they can lead to increased memory usage since new objects are created instead of modifying existing ones. However, the trade-off often leads to more robust code.
