Conventions

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

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "If the Ractive component has a friends property, then we will render a list of users."

A block of code is set as follows:

<li class="right"><a on-click="goto:logout">Logout</a></li>
<li class="right"><a on-click="goto:profile">Profile</a></li>
<li class="right"><a on-click="goto:find-friends">Find  friends</a></li>

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

sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "It shows their name and a Add as a friend button."
