A programming paradigm known as functional programming avoids state and changeable data and regards computing as the evaluation of mathematical functions. In other words, immutable variables and side-effect-free code are encouraged by functional programming (FP). It uses a declarative programming approach. In contrast to an imperative style, where the primary focus is "how to solve," it places a greater emphasis on "what to solve."
