What is the Circuit Breaker pattern in JavaScript?

The Circuit Breaker pattern is a design pattern used to prevent an application from repeatedly trying to execute an operation that is likely to fail. It helps to improve the stability and resilience of applications.

Can you explain how it works with an example?

MagicBuddy

Sure! Imagine a service that calls an external API. If the API fails multiple times, the Circuit Breaker will 'trip' and stop further calls for a specified time, allowing the service to recover.

How do I implement it in my JavaScript code?

You can implement it using libraries like 'opossum' or by creating a custom Circuit Breaker class that tracks the state of the service and manages the calls.
