Functional programming is taking off today, and numerous languages like F#, RUST, and GO are among the most popular languages that promote functional programming.
Functional Programming is the method of creating software using pure functions, which avoid sharing state, mutable data and side-effects. Functional programming is more declarative than imperative, and the state of the application can flow by pure functionalities. Contrast this with object-oriented programming, where the application's state is typically shared and integrated with methods that are part of objects.
Functional programming can be described as a paradigm of programming. It is a method to think about the construction of software based on a set of fundamental, basic principles (listed in the previous paragraph). Additional examples of programming models are procedural programming and object-oriented programming.
Functional code is generally less cluttered, more predictable, and more easy to test than object-oriented or imperative code. However, if you're not familiar with it or the typical patterns, it entails, functional code could appear denser and the literature on it can be challenging to comprehend for newcomers.
