What are Worker Threads?
Worker Threads allow JavaScript code to run in separate threads within the same Node.js process. They are particularly useful for CPU-intensive JavaScript work that would otherwise block the main event-loop thread. Workers can communicate with the main thread using message passing and can also use shared memory mechanisms where appropriate.
Key Takeaways
- Worker Threads provide additional JavaScript threads.
- They are useful for CPU-intensive workloads.
