TypeScript Generics
Task
Write a TypeScript function groupBy<T, K extends keyof T>(items: T[], key: K): Record<string, T[]> that groups an array of objects by a given key. It should be fully type-safe — the key parameter should only accept keys of T, and the compiler should catch invalid keys at build time.
Include an example usage with an array of { name: string, department: string, level: number }.
