What are the best practices for writing immutable code?

What are the best practices for writing immutable code?

Writing immutable code involves several best practices: 1. Use immutable data structures, 2. Avoid side effects, 3. Favor pure functions, and 4. Leverage libraries that support immutability.

Can you explain why immutability is important?

Immutability is important because it helps prevent unintended side effects, makes code easier to reason about, and enhances performance in concurrent programming.

What are some common pitfalls when working with immutable code?

Common pitfalls include overusing immutability, which can lead to performance issues, and misunderstanding how to effectively manage state changes.

Are there specific programming languages that support immutability better?

Yes, languages like Haskell, Scala, and Clojure are designed with immutability in mind, while languages like JavaScript and Python have libraries that facilitate immutable programming.
