Super TypeScript II Turbo – FP Remix
summary
Shows concrete TypeScript code that uses pure functions, higher‑order functions and generics to build pipelines like updatePlayer = compose(updateHealth, compose(updateAnimation, updatePosition)) and maps/filters that produce a new list of injured enemies after dealing damage. Demonstrates how compose and typed transforms preserve input/output types across arrays, promises and observables, and how Readonly plus Pick and Record enforce surface immutability (with the caveat that private mutable state still works). Code compiles and behavior remains predictable.
