This is very similar to how google works. Everyone knows HOW to google, so when you get a query like "What is the purpose of design patterns", you can very quickly use this common interface to solve a problem.

设计模式也解决了有关可用性和可维护性特定的编程挑战。拿起书四的刚和拥有它。

Design Patterns also solve specific programming challenges regarding usability and maintainability. Pick up the Gang of Four book and have at it.
