Sometimes in programming, you find the same problem coming up quite often. It is usually worthwhile working out a standard solution to the problem, or finding out if someone else already has. This solution is called a design pattern. It isn’t actually a piece of code itself, but it is a way of solving a particular recurring problem.
Once you have worked out a design pattern, you can often come up with some code to implement all or part of it, or at least a set of utility functions that will help.
