Route by Pattern
- Context cancellation → see context/
- Goroutine leaks → see goroutines/
- Channel patterns → see channels/
- Sync primitives → see sync/
Quick Check
- Every goroutine has exit path
- Context passed and checked
- Channels closed by sender only
- WaitGroup Add before go
Common Pitfalls
- Launching goroutines without shutdown mechanism
- Not propagating context through call chains
- Closing channels from receiver side
- Using WaitGroup counter incorrectly
Decision Tree
Need coordination? → Use context for cancellation
Need data flow? → Use channels
Need to wait? → Use sync.WaitGroup
Need mutual exclusion? → Use sync.Mutex
