In software development, we often come across problems that share similarities regardless of the environment they appear in. Although the implementation details are crucial to solve the task at hand, we may abstract from these particularities to find the common practices that are generically applicable.

Design patterns are a collection of reusable and tested solutions to recurring problems in engineering. They make our software more modular, maintainable, and extensible. Moreover, these patterns provide a common language for developers, making them an excellent tool for effective communication when problem-solving in teams.
