Course Summary

Home > Courses >Back-End Development >GoLang >Introduction to Go

The Introduction to Go training course is project ­based: building a shared “game” server that students can use to interact with each other via defined APIs. There is also a strong “code reading” portion, whereby students can check their understanding of GoLang by reading and modifying open ­source GoLang projects. This course will explore concurrency (by diving into more concurrency patterns) and the standard library, as well as providing more coding activities using popular Go libraries/frameworks (such as logging and microservices).
