Introduction to design patterns 🧮

Hey there, welcome to this YouTube Shorts on Introduction to Design Patterns! In this short video, I'll be introducing the concept of design patterns and their importance in software engineering.

Design patterns are reusable solutions to commonly occurring software engineering problems. They are like blueprints that developers can use to solve recurring problems in software design. These patterns help to create more flexible, maintainable, and scalable software applications.

The concept of design patterns was introduced by the Gang of Four (GoF), a group of four software developers who wrote a book called "Design Patterns: Elements of Reusable Object-Oriented Software". This book provides a catalogue of 23 design patterns that are classified into three categories: creational, structural, and behavioral patterns.

Creational patterns are used to create objects in a system, while structural patterns are used to define the relationships between objects. Behavioral patterns define how objects interact with each other to achieve a common goal.

Design patterns are essential in software engineering because they provide a common language for developers to communicate and collaborate effectively. They also help to avoid reinventing the wheel by providing proven solutions to common problems.
