What are design patterns?

Design patterns are reusable solutions to common software design problems. They are templates or blueprints that provide a structured way to solve recurring design challenges in software development. Design patterns help developers create more maintainable, efficient, and scalable software by promoting best practices and proven solutions to common problems. These patterns encapsulate the knowledge and experience of experienced software designers, making it easier for others to apply these solutions in their own projects. Design patterns are an essential part of software engineering and contribute to the development of high-quality and robust software systems.
