Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. In this article, we'll explore the basics of functional programming and why it's gaining popularity among developers.

Key Concepts

  • Pure Functions: Functions that always return the same output for the same input and have no side effects.
  • Immutability: Data that cannot be changed after it's created.
  • Higher-Order Functions: Functions that take other functions as arguments or return them as results.
  • Recursion: A method of solving problems where the solution depends on solutions to smaller instances of the same problem.

Benefits of Functional Programming

  • Increased Code Readability: The use of pure functions and immutability makes code easier to understand and reason about.
  • Improved Maintainability: Functions are self-contained and easier to test and debug.
  • Concurrency: Functional programming is well-suited for concurrent programming due to its stateless nature.
