Pure functions can be visualized as static mappings from inputs -> outputs. It's like a simple table mapping inputs to outputs. Given a set of inputs, you are guaranteed the same outputs on every invocation. In a complex world with many hidden aspects, unleashing unpleasant surprises all the time, working on purely functional components makes it easier to: 1. understand 2. test 3. debug 4. extend These are significant benefits of the functional approach (at function/component level) in my pov.
