How can I optimize recursion in functional programming?

How can I optimize recursion in functional programming?

You can optimize recursion by using techniques like tail recursion, memoization, and transforming recursive functions into iterative ones.

What is tail recursion and how does it help?

Tail recursion is a form of recursion where the recursive call is the last operation in the function. It helps by allowing the compiler to optimize the call stack, reducing memory usage.

Can you explain memoization?

Memoization is an optimization technique that stores the results of expensive function calls and returns the cached result when the same inputs occur again.

Are there any downsides to using recursion?

Yes, recursion can lead to stack overflow if the recursion depth is too high, and it may also be less efficient than iterative solutions in some cases.
