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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

connect(mapStateToProps, mapDispatchToProps, mergeProps, options)(Component)

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

import { observable, autorun, action } from 'mobx';

let cart = observable({
    itemCount: 0,
    modified: new Date(),
});

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

$ mkdir css
$ cd css

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."
