What are the benefits of using design patterns?
Design patterns help the programmer apply already-proven approaches to common problems. There will be less time wasted in searching for the proper solution or fixing a design issue after a sub-optimal implementation. Anti-patterns provide additional guidance for avoiding common design flaws.
