An example of an AI chatbot conversation about common mistakes using WaitGroup in Go.
What are the common mistakes when using WaitGroup in Go?
Some common mistakes include not calling Done(), using WaitGroup in a loop without proper synchronization, and not handling goroutine panics.
Can you explain why not calling Done() is a mistake?
Not calling Done() can lead to deadlocks because the WaitGroup will never reach zero, causing the program to hang.
What happens if I use WaitGroup in a loop?
Using WaitGroup in a loop without proper synchronization can cause race conditions, leading to unpredictable behavior.
How can I handle panics in goroutines with WaitGroup?
You can recover from panics within the goroutine and ensure that Done() is called in a deferred function to avoid deadlocks.
