Overview of this book

<p>With its C-like speed, simplicity, and power for a growing number of system-level programming domains, Go has become increasingly popular among programmers. Hands-On Go Programming teaches you the Go programming by solving commonly faced problems with the help of recipes. You will start by installing Go binaries and get familiar with the tools used for developing an application. Once you have understood these tasks, you will be able to manipulate strings and use them in built-in function constructs to create a complex value from two floating-point values. You will discover how to perform an arithmetic operation date and time, along with parsing them from string values. In addition to this, you will cover concurrency in Go, performing various web programming tasks, implementing system programming, reading and writing files, and honing many fundamental Go programming skills such as proper error handling and logging, among others. Whether you are an expert programmer or newbie, this book helps you understand how various answers are programmed in the Go language.</p>

Chapter 5. Maps and Arrays

In this chapter, you will learn how to work with maps and arrays in Go.You will see practical examples of manipulating and iterating arrays, merging arrays and maps, and testing whether a key is present in a map. We will go through the following recipes in this chapter:

  • Extracting unique elements from a list
  • Finding an element from an array
  • Reverting an array
  • Iterating over an array
  • Converting a map into an array of keys and values
  • Merging arrays
  • Merging maps
  • Testing for the presence of a key in a map
