Goroutines vs Threads: Which is Better for Performance?

What are the main differences between goroutines and threads?

Goroutines are lightweight, managed by the Go runtime, while threads are managed by the OS and are heavier.

How do goroutines improve performance in Go applications?

Goroutines allow concurrent execution with less overhead, enabling better resource utilization and scalability.

Can you give an example of when to use goroutines over threads?

Use goroutines for I/O-bound tasks where you need to handle many connections, like web servers, due to their efficiency.

Are there any downsides to using goroutines?

Yes, goroutines can lead to complexity in error handling and debugging, especially with many concurrent operations.
