function mapObject<K, V, U>(
  record: ReadonlyRecord<K, V>,
  fn: (value: V, key: K) => U,
): ReadonlyRecord<K, U>;

Defined in: packages/common/src/Object.ts:144

Maps a ReadonlyRecord<K, V> to a new ReadonlyRecord<K, U>, preserving branded key types (e.g., type Id = 'id' & string) lost by Object.entries. Uses K extends string for precision.
