FUNCTORS, APPLICATIVES, AND MONADS: THE SCARY WORDS YOU ALREADY UNDERSTAND

Summary from the TLDR Dev newsletter

Functors, Applicatives, and Monads are common patterns developers already use. A Functor allows applying a function to a wrapped value (like `Maybe.map`). An Applicative combines multiple wrapped values with a multi-argument function (like `Maybe.map2`). A Monad handles chaining operations where each step returns a wrapped value, preventing nested containers (like `Maybe.andThen`).
