What is Functional Programming?
Functional programming is a programming paradigm that emphasizes the use of pure functions, immutability, and recursion. It’s a way to write code that is more predictable, easier to reason about, and less prone to bugs.
In functional programming, programs are composed of small, self-contained functions that take input and produce output without modifying external state. This approach allows for better modularity, reusability, and composability of code.
Key Features of Functional Programming
Some key features of functional programming include:
* Pure functions: Functions that always return the same output given the same inputs, with no side effects.
* Immutability: Data structures are immutable by default, making it easier to reason about and predict program behavior.
* Recursion: Recursive function calls allow for efficient processing of complex data.
Functional programming has many benefits, including improved code quality, reduced bugs, and increased developer productivity. It’s a powerful tool that can help you write more robust, maintainable, and scalable software.
