How does publish-subscribe work?

Can you explain how the publish-subscribe model works?

Sure! The publish-subscribe model is a messaging pattern where senders (publishers) send messages without knowing who will receive them (subscribers).

How do publishers and subscribers find each other?

They typically use a message broker or a middleware that manages the communication between them, allowing subscribers to express interest in certain messages.

What are some advantages of using this model?

Some advantages include decoupling of components, scalability, and the ability to handle multiple subscribers efficiently.

Can you give me an example of where this is used?

Certainly! It's commonly used in event-driven architectures, like in social media platforms where users can subscribe to updates from others.
