1. An Introduction Shane Logsdon Go  
2. Why Use Go •  Standard Library •  Tooling •  Compiling •  Concurrency •  Deployment •  And more
3. Standard Library •  Provides large chunk of necessary functionality •  encoding/json & encoding/xml •  flag •  io/ioutil •  net/http •  net/http/httptest •  testing •  Etc. •  External libraries offer convenience
4. Tooling •  go fmt •  go test •  go doc •  Community supplied
5. Compiling •  Compilation within seconds •  No waiting for VM to spin up •  Target multiple platforms with cross compilation •  Increase development efficiency
6. Concurrency •  Goroutines •  lightweight asynchronous “processes” •  Channels •  transfer data between goroutines •  Example •  server handles individual requests in separate goroutines
7. Deployment •  Can be single binary file •  Built for host platform and OS •  Quick compile process -> build on host •  Easy integration with CI/CD services
