What are the best practices for using immutable data in real-world applications?

Using immutable data can enhance predictability and reduce bugs. Key practices include using data structures that are inherently immutable, like tuples in Python or Immutable.js in JavaScript.

Can you give me an example of an immutable data structure?

Sure! An example is a List in Scala, which is immutable. Once created, you cannot change its elements, but you can create a new list based on it.

What are the benefits of using immutable data?

Benefits include easier debugging, improved performance in concurrent programming, and enhanced data integrity since the data cannot be altered.

Are there any downsides to using immutable data?

Yes, the main downside is that it can lead to increased memory usage since new copies of data structures are created instead of modifying existing ones.
