There are 4 modules in this course

Continue your exploration of the Go programming language as you learn about functions, methods, and interfaces. Topics include the implementation of functions, function types, object-orientation in Go, methods, and class instantiation. As with the first course in this series, you’ll have an opportunity to create your own Go applications so you can practice what you’re learning. The first module introduces the concept of functions and shows you how to use them to manipulate data programmatically. Once again, the treatment of the topic begins at a fairly rudimentary level to ensure everyone is starting from the same point in terms of basic concepts.

Learned a bit on go syntax and how polymorphism works. Thanks the instructor. Good learning experience overall.

One of the best if not the best course on Golang that I have taken. For a long time I struggled with some very fundamental concepts in Go, but today, I am confident of my knowledge in it.

Very nice course, it gives good understanding of OOP features of Go. I liked a lot course's assignments also. Thanks, Pr. Ian Harris !
