MongoDB: deleting a document from a collection

async function deleteCourse(id) {
  const result = await Course.deleteOne({ id: id });
  console.log(result);
}

Use findByIdAndRemove([id]) if you want to return the value that is deleted.

If we were to pass a query object that matches multiple documents in the database to deleteOne it would only delete the first document returned. To delete all use deleteMany.
