What is the Go Sync Package?

Can you explain what the Go Sync Package is?

The Go Sync Package provides synchronization primitives for concurrent programming in Go, like Mutex and WaitGroup.

How do I use a Mutex in my Go program?

You can use a Mutex by creating an instance of sync.Mutex and then using Lock() and Unlock() methods to protect shared resources.

What is a WaitGroup and when should I use it?

A WaitGroup is used to wait for a collection of goroutines to finish executing. You add to the WaitGroup before starting goroutines and call Done() when they finish.

Are there any examples of using these in a real application?

Yes, you can find examples in the Go documentation or GitHub repositories that demonstrate using Mutex and WaitGroup in various scenarios.
