What are wait groups in Go?
An example of an AI chatbot conversation about wait groups in Go programming.
Can you explain what wait groups are in Go?
Sure! Wait groups in Go are used to wait for a collection of goroutines to finish executing.
How do I use a wait group in my code?
You can use the sync.WaitGroup type. First, create a wait group, then call Add(n) to set the number of goroutines to wait for.
What happens if I forget to call Done()?
If you forget to call Done(), the wait group will never reach zero, causing your program to hang indefinitely.
