Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state or mutable data. Here's a quick guide to its core concepts:

🔧 Key Principles

  • Pure Functions
    No side effects, output depends only on inputs.

    Pure Function

  • Immutable Data
    Data cannot be changed after creation.

    Immutable Data

  • Higher-Order Functions
    Functions that take other functions as arguments or return them.

    Higher Order Function

  • Recursion
    Functions that call themselves to solve subproblems.

    Recursion

📘 Why Use It?

  • Easier parallel processing
  • Fewer bugs from state management
  • More concise code
  • Parallel Processing
