Conventions used

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

CodeInText: 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: "The bytes library provides a number of convenient functions when working with data."

A block of code is set as follows:

                b, err := ioutil.ReadAll(r)
                if err != nil {
                    return "", err
                }
                return string(b), nil
        }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

        package bytestrings
        
        import (
                "bytes"
                "io"
                "io/ioutil"
        )

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

$ go mod init github.com/PacktPublishing/Go-Programming-Cookbook-Second-Edition/Chapter01/interfaces

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."

Warnings or important notes appear like this.

Tips and tricks appear like this.
