 *
 * Utility type to get a value from an object by a string path
 *
 * 문자열 경로로 객체에서 값을 가져오는 유틸리티 타입
 *
 * @param T Object type to get the value from / 값을 가져올 객체 타입
 *
 * @param K String path to get the value from / 값을 가져올 문자열 경로
 *
 * @returns Value of the object at the path / 경로에 있는 객체의 값
 *
 * @example
 * type cases = [

 *   Expect<Equal<GetToObject<{ a: 1 }, 'b'>, never>>,
