The proxy object has the same interface as a service, which makes it ...Refactoring is a systematic process of improving codewithout creating new functionality that can transforma mess into clean code and simple design. Dirty code is result of inexperiencemultiplied by tight deadlines,mismanagement, and nastyshortcuts taken during thedevelopment process.
