What are the key benefits of using Redis Pub/Sub in a Node.js application?

Key benefits include: decoupling of publishers and subscribers, enabling asynchronous communication; scalability, as multiple subscribers can listen to the same channel; real-time updates, allowing for instant message delivery; and efficiency, as Redis is designed for high-performance in-memory data operations. This makes it ideal for scenarios like chat applications, real-time dashboards, and microservice communication.
