Learning Go (2021)

Course details

What is Go? Go is a next-generation, open-source programming language created by Google for building systems, web, and other applications. This course is designed to help developers get started with Go, covering its core language elements and syntax. David Gassner introduces tools and skills used in a Go workflow—including Go Playground, an online tool that takes Go development off the desktop. He also covers basic programming tasks: managing values, using math operators, storing values as complex types, and managing program flow. Plus, learn how to create reusable Go code, read and write files, and make simple web requests.

Topics include:
Installing Go development tools and Visual Studio Code
Exploring variables, constants, and types
Storing ordered and unordered values
Grouping related values in structs
Programming conditional logic and loops
Defining and calling functions
Handling errors
Working with files
