What are the limitations on the number of goroutines that can be run simultaneously in a program?

In Go, the number of concurrently running goroutines does not have a strict limit; it depends on the available system resources such as memory and CPU time.

Goroutines are very lightweight compared to OS threads, so it is possible to run dozens or hundreds of thousands of goroutines in a single program. However, having too many goroutines can lead to increased memory consumption and scheduling overhead.

It is important to control the number of active goroutines and use synchronization and limiting mechanisms, such as semaphores or worker pools, to avoid excessive load.
