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] Control flow within a Go program can be implemented using the standard if/else statement. In the example shown here, line eight defines and sets the population variable with the value of 5,500. 

Lines 10 through to 16 implement a simple if/else block, which tests whether the current value is within a certain range. Lines 18 to 20 implement another if statement, this time without the else portion. This also demonstrates that variables can be declared within the if statement itself, but need to be declared before the conditional or test. Running this example results in the following output, "medium," followed by, "Its on!" 

In summary, you've just observed the basic form of the if/else statement and how it can be used perform control flow. If/else statements require curly brackets and do not require parentheses around the test.
