PartialDeep type

Like Partial but recursive

Signature:

export declare type PartialDeep<T> = T extends Builtin
  ? T
  : T extends Map<infer K, infer V>
  ? Map<PartialDeep<K>, PartialDeep<V>>
  : T extends ReadonlyMap<infer K, infer V>
  ? ReadonlyMap<PartialDeep<K>, PartialDeep<V>>
  : T extends WeakMap<infer K, infer V>
  ? WeakMap<PartialDeep<K>, PartialDeep<V>>
  : T extends Set<infer U>
  ? Set<PartialDeep<U>>
  : T extends ReadonlySet<infer U>
  ? ReadonlySet<PartialDeep<U>>
  : T extends WeakSet<infer U>
  ? WeakSet<PartialDeep<U>>
  : T extends Array<infer U>
  ? T extends IsTuple<T>
    ? {
        [K in keyof T]?: PartialDeep<T[K]>;
      }
    : Array<PartialDeep<U>>
  : T extends Promise<infer U>
  ? Promise<PartialDeep<U>>
  : T extends {}
  ? {
      [K in keyof T]?: PartialDeep<T[K]>;
    }
  : Partial<T>;
