Learning Go - a free PDF for learning the Go language.
The book currently consists of the following chapters:
- Introduction: Details the lineage of the language Go and shows the types, variables and control structures.
- Functions: How to make and use functions.
- Packages: Functions and data are grouped together in packages. Here you will see how to make your own package. How to unit test your package is also described.
- Beyond the basics: Learn how to create your own data types and define functions on them (called methods in Go).
- Interfaces: Go does not support Object Orientation in the traditional sense. In Go the central concept is interfaces.
- Concurrency: With the go keyword functions can be started in separate routines (called goroutines). Communication with these goroutines is done via channels.
- Communication : How to create/read/write from and to files. And how to do networking.
Each chapter concludes with a number of exercises with answers to help you get some hands-on experience. Currently there are more than 30 exercises.
