Go Programming Language - Learning The Go Lang way
The document summarizes a presentation on the Go programming language. It covers the basics of Go including that it is open source, has no semicolons, uses namespaces and the "main" keyword. It then walks through examples of printing multiplication tables, using arrays and slices, testing code, concurrency using goroutines and channels, working with structs and interfaces. The presentation highlights Go's simplicity, reliability and efficiency and provides a GitHub link for the example code.
