Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “When calling the rollDice function, the output is not consistent. If it were consistently outputting the same number, it would be a pretty bad randomization function.”

A block of code is set as follows:

func rollDice() int {
	return rand.Intn(6)
}

Any command-line input or output is written as follows:

go test -bench=.

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “In this main function, we are first defining a deferred function that runs at the end of main function, just before function exit.”
