Design patterns are formalized best practices that the programmer can use tosolve common problems when designing an application or system.

Design patterns can speed up the development process by providing tested, provendevelopment paradigms.

Reusing design patterns helps to prevent subtle issues that can cause majorproblems, and it also improves code readability for coders and architects whoare familiar with the patterns.

Before you dive into the material, you should be familiar with variousProgramming/Software Design Principles.

All designs should be as simple as possible. You should start with KISS, YAGNI,and Do The Simplest Thing That Could Possibly Work principles. Complexity andpatterns should only be introduced when they are needed for practicalextensibility.

Once you are familiar with these concepts you can start drilling down intopatterns by any of the following approaches

• Using difficulty tags,Difficulty-Beginner,Difficulty-Intermediate &Difficulty-Expert.
• Using pattern categories,Creational,Behavioral and others.
• Search for a specific pattern. Can't find one? Please report a new patternhere.
