Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

The Option type is a powerful tool for handling values that may or may not be present, inspired by functional programming languages like Rust and Haskell. It provides a type-safe way to avoid common errors associated with null or undefined by explicitly representing the absence of a value.
