What are some examples of functional programming in different languages?

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions. Languages like Haskell, Scala, and F# are designed for functional programming, while others like JavaScript and Python support it as well. Would you like to know specific features of these languages?

Yes, can you explain how Haskell implements functional programming?

Haskell is a purely functional programming language, meaning that functions are first-class citizens and side effects are minimized. It uses lazy evaluation, allowing for the creation of infinite data structures and more efficient memory usage. Would you like to see a code example?

That sounds interesting! Please show me a simple Haskell function.

Sure! Here's a simple Haskell function that calculates the factorial of a number:

factorial :: Integer -> Integer
factorial 0 = 1
factorial n = n * factorial (n - 1)

This function uses recursion, a common technique in functional programming. Do you want to explore more examples?
