Functions

May 1, 2024 Updated May 8, 2025 27 minute read

At a fundamental level, a function is a rule or a process that takes an input and produces a corresponding output. Think of it like a vending machine: you put in money (input) and select an item (another input, or part of the input process), and the machine dispenses a product (output). This input-output relationship is the core idea behind functions, a concept that is surprisingly versatile and appears in many different fields.
