Often technical jargon can be ambiguous and mislead developers, a perfect example of this is the term “functional programming” (FP) or “Object oriented programming ” (OOP). It’s easy to assume that FP is just writing your code in a series of function...

Hashnode is a community-driven platform for developers to share knowledge, ask questions, and connect with peers in the tech industry. Developers can learn about new technologies, programming languages, and software development methodologies, engaging in discussions, and networking with fellow developers to expand their knowledge and grow their careers in tech.

Functional Programming is the use of Pure Functions to create extremely explicit and easily testable code. By avoiding sharing/mutating state and reducing side-effects FP lowers the cognitive burden of adding functionality to a growing code base. Pure functions make testing easier, any good codebase has tests and when maintaining tests you want to make sure your testing all possible code paths.
