Recursive Types

A key concept to explore is the creation of recursive types. These are types that can refer to themselves, which is useful for defining nested data structures.

Example Problem:

  • Define a type called NestedPath that can represent a dot-separated path to any property within a deeply nested object.

    For example, given an object like:

    const obj = {
  a: {
    b: {
      c: 1
    }
  },
  d: 2
};

    The NestedPath type should allow for strings like "d", "a.b", and "a.b.c", but not invalid paths like "a.c".
