Design patterns are reusable solutions to commonly occurring programming problems. In other words, they can act as templates to solve problems we encounter in our day to day programming. They help make our code more structured, robust, scalable and maintainable.

In this video, we discuss what design patterns are and why should a software developer care about them. We also discuss how design patterns can be effective tools of communication and how we can combine multiple patterns to achieve something. We briefly touch on the types of design patterns as well: Creational, Structural and Behavioral. We also cover why there are so many design patterns under those three classifications and when to use which one.
