Functional Programming
Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions, emphasizing immutability and pure functions.
Overview
Functional programming emphasizes writing code using pure functions, immutability, and avoiding side effects. Functional programming can make code more predictable and easier to test.
Functional programming concepts include higher-order functions, immutability, recursion, and function composition, which can be applied in many programming languages.

Key Concepts
Pure Functions
Write functions that always return the same output for the same input and have no side effects.
Immutability
Use immutable data structures that cannot be changed after creation, reducing bugs and improving predictability.
Higher-Order Functions
Use functions that take other functions as arguments or return functions, enabling powerful abstractions.
Function Composition
Combine simple functions to build complex functionality through composition.
