Design Pattern

• Design Pattern is a general reusable solution to a common problem in software design.

• Blue print that you can follow to solve a particular design issue in the code.

• It is not specific to any programming language and can be applied in various contexts.

Why?

1. Reusability: Design patterns provide solutions that can be reused in different parts of your application or in different projects.
2. Efficiency: They help you solve problems more quickly by providing a tried-and-tested approach.
3. Maintainability: Code that follows design patterns is often easier to understand, maintain, and extend.
4. Communication: They provide a common vocabulary for developers, making it easier to discuss and share design ideas.
