The Observer Pattern in Programming
The podcast discusses the observer pattern, a design pattern in computer programming. The observer pattern is widely used in various programming contexts, including game development and front-end frameworks. It allows different parts of a system to communicate and react to events without being tightly coupled. The observer pattern consists of two key components: the observer, which is notified when an event occurs, and the subject, which triggers the event and maintains a list of observers.
