How do you prevent event-loop blocking?
Avoid expensive synchronous operations and long-running CPU-intensive JavaScript on the main thread. Large computations can be moved to Worker Threads or separate processes. Large datasets should be processed incrementally where possible, and algorithms should be optimized. Monitoring event-loop latency can also help detect blocking problems in production.
Key Takeaways
- Avoid long synchronous operations on the event-loop thread.
- Use Worker Threads for suitable CPU-heavy JavaScript workloads.
- Optimize algorithms and monitor event-loop latency.
