Functional Programming

Functional programming is a programming paradigm that emphasizes the use of pure functions, immutability, and the avoidance of changing state, making it a popular approach for developing predictable, modular, and reusable code. As a research area, functional programming continues to influence the design of programming languages, software development methodologies, and data processing frameworks, attracting interest from both academia and industry for its potential to improve code maintainability, scalability, and concurrency.
