What are goroutines and how do they perform in Go?

Goroutines are lightweight threads managed by the Go runtime. They allow concurrent execution of functions, making it easier to write programs that can perform multiple tasks simultaneously.

How do goroutines compare to traditional threads in terms of performance?

Goroutines are generally more efficient than traditional threads. They have a smaller memory footprint and are managed by the Go scheduler, which allows for better resource utilization.

Can you explain how to create and manage goroutines?

To create a goroutine, simply use the go keyword followed by a function call. The Go runtime handles the scheduling and management of these goroutines automatically.

What are some common pitfalls when using goroutines?

Common pitfalls include race conditions, not handling errors properly, and failing to synchronize access to shared resources.
