How can I optimize pure functions in my code?

To optimize pure functions, focus on minimizing side effects, using memoization, and ensuring they are stateless.

What is memoization and how does it help?

Memoization is a technique that caches the results of function calls, improving performance by avoiding repeated calculations.

Can you give me an example of a pure function?

Sure! A simple example is a function that adds two numbers: function add(a, b) { return a + b; }.

Are there any downsides to using pure functions?

While pure functions are great for predictability and testing, they can sometimes lead to performance issues if not optimized properly.
