Description

If you're thinking about engineering the next big dotcom application then you should seriously consider using Go!! 

The Go Programming Language is without doubt one of the hottest languages to learn, particularly in this cloud native era. More and more companies are adopting Go to engineer highly performant, stable and maintainable applications. Popular projects such as Docker, Kubernetes, Terraform, Etcd, Istio, InfluxDB have all been built successfully using Go!! 

This introductory level training course is designed to bring you quickly up to speed with the many key features that the Go programming language provides. You'll also learn how to setup your own Go development environment - consisting of the Go toolchain, Visual Studio Code, and several related Go based extensions - all to ensure that you are able to be productive writing your own source code.

We’d love to get your feedback on this course, so please give it a rating when you’re finished. If you have any queries or suggestions, please contact us at support@cloudacademy.com.

Transcript

- [Jeremy Cook] The coding example displayed here demonstrates how to implement a method with a non-struct typed receiver argument. 

In this example, the up method defined on lines eight to 11 implements a simple string upper casing function. The receiver type is of type upstring, and is a custom non-struct string based type declared on line six. With this in place, the up method can now be invoked using dot notation. 

This is demonstrated within the main function on line 15. Let's now run this example and see what happens. And, as expected, the output is the string cloudacademy uppercased. Changing the cloudacademy message to devops and rerunning the program again provides the expected result. 

In summary, you've just observed how receiver arguments can be declared as non-struct types.
