In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Create another file, called MockSharePointClient.ts, in the same folder that the web part is located."

A block of code is set as follows:

import { Environment, EnvironmentType } from '@microsoft/sp-core-library'; 
import { ISPListItem } from "./ISPListItem"; 
import MockSharePointClient from "./MockSharePointClient"; 

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

    gulp serve 

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Write in Team site name, for example, SPFX-testing."
