Coordinate safe, structured concurrency in Go to prevent leaks and ensure errors propagate correctly.
Demonstrate a minimal Go example using errgroup.WithContext to run five concurrent tasks with proper cancellation and error handling.

Prevent goroutine leaks by applying structured concurrency with errgroup.WithContext to ensure proper context propagation, explicit cancellation, and resource cleanup across workers.
The best way to propagate errors across goroutines is using errgroup.WithContext, which automatically cancels the context when one worker returns an error, ensuring safe structured concurrency.
Implement bounded concurrency for parallel processing by applying errgroup.SetLimit or channel-based worker pools to restrict active goroutines and prevent resource exhaustion.
Yes, errgroup works seamlessly with context timeouts and graceful shutdown by propagating the context across workers, ensuring concurrent tasks cancel safely and clean up resources properly.
Use channel-based worker pools instead of errgroup.SetLimit when you need explicit coordination logic for complex batch processing, rather than just bounding concurrency for parallel tasks.
Race conditions occur during parallel task execution without proper context propagation and bounded concurrency, which you can fix by applying structured concurrency patterns and explicit error handling.
