Learning Go

Course details

Go, also known as Golang, is one of the most popular programming languages for command line applications, web services, and the cloud. In this course, learn the basics of Go, using GitHub Codespaces as your development environment. See how to use the fundamental building blocks of Go applications: variables, collections, conditional logic and loops. Instructor David Gassner also covers practical uses of Go, such as working with files, requesting and processing content from the web, and working with data structured as JSON strings.

Learning objectives
Use variables, constants, and types.
Group related values in structs.
Create conditional logic and loops.
Program concurrent operations with goroutines.
Work with files and web requests.
