Type as string path of object keys

Question

interface Obj {
  a: any;
  b: {
   c: any;
   d: any;
  }
  c: {
    d: any;
  }[];
}

get(obj: Obj, path: string) {
}

I'd like to type the path to force user to pass only keys available in the obj. get(obj: Obj, path: keyof Obj){} works only for the first level.

Expected result is being able to pass as the path: a, b, b.c, b.d, c, c[0], c[0].d. Is typescript's way of typing able to solve this problem?
