  2. Basics: Types, variables and control structures.
  3. Functions: How to make and use functions.
  4. Packages: Functions and data is grouped together in packages. Here you will see how to make your own package. How to unit test your package is also described.
  5. Beyond the basics: Learn how to create your own data types and define function on them (called methods in Go).
  6. Interfaces: Go does not support Object Orientation in the traditional sense. In Go the central concept is interfaces.
  7. Concurrency: With the go keyword function can be started in separate routines (called goroutines). Communication with those goroutines is done via channels.
