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 email@example.com.
By completing this course, you will:
- Learn about what makes Go a great language
- Learn how to install the Go toolchain
- Learn how to setup Visual Studio Code to edit and debug Go programs
- Learn how to work with the Go Playground to test and run snippets of Go code
- Learn and understand the basic Go language syntax and features
- Learn how to use the Go tool chain commands to compile, test, and manage Go code
- And finally, you’ll learn how to work with and manage Go modules for module dependency management
This course is intended for:
- Anyone interested in learning the Go Programming Language
- Software Developers interested in using Go to compile and test Go based applications
- DevOps practitioners looking to learn about Go to support Go based applications
To get the most from this course, you should have at least:
- A basic understanding of software development and the software development life cycle
All sample Go source code as used and demonstrated within this course can be found here:
- [Jeremy Cook] The const keyword is used to define constants. Constants, once declared and initialized, cannot be reassigned at any time afterwards.
Constants can be declared anywhere that a variable is declared, and can be declared as any data type, such as string, int, Boolean, etc. The data type doesn't need to be provided, since, again, the compiler can simply infer the data type at compile time, as it does on line 12 in the given example. Constants are scoped, that is, they exist only within the scope that they were declared within. This can be seen in the given example, again, where attempting to print out the color constant on line 23 would result in a compile time error, since it was declared within the scope of the if statement. Running this example prints out the expected values 10,000 and CloudAcademy.
Therefore, in summary, you've just observed how to declare a constant using the const keyword, that constants are scoped, they only exist within the scope that they were declared within, constants are typed, constants must have a defined value at the time of declaration, and constants cannot be reassigned anytime after the initial declaration.
