Next Steps

What you can do now

• Install Go and run package main programs
• Use structs, slices, maps, and control flow
• Write functions, methods, and small interfaces
• Check errors, try goroutines/channels, and run go test

Practice ideas

Build a CLI that reads a file, counts words with a map, and prints results with fmt. Add tests for the counting function.

Common traps

• Ignoring returned errors
• Writing to a nil map
• Sharing structs across goroutines without synchronization
• Forgetting that main exit stops other goroutines

Where to go next

• Context for cancellation
• JSON encoding with encoding/json
• HTTP servers with net/http
• Generics in modern Go
• Workspaces and larger module layouts
