Go in Action. Chapter 2. William Kennedy, Brian Ketelsen and Erik St. Martin

Go has its own elegance and programming idioms that make the language productive and fun to code in. The language designers set out to create a language that would let them be productive without losing access to the lower-level programming constructs they needed.
This balance is achieved through a minimized set of keywords, built-in functions, and syntax. Go also provides a comprehensive standard library. The standard library provides all the core packages programmers need to build real-world web- and network-based programs.
To see this in action, we’ll review a complete Go program that implements functionality that can be found in many Go programs being developed today. The program pulls different data feeds from the web and compares the content against a search term.
The content that matches is then displayed in the terminal window.
