It is considered good practice to only throw the Error object itself or an object using the Error object as base objects for user-defined exceptions and to pass instances of the built-in Error object to the reject() function for user-defined errors in Promises. The fundamental benefit of Error objects is that they automatically keep track of where they were built and originated.
