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 text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "If it is, then we render the users/profile.jade template with req.user as the data."

A block of code is set as follows:

var express = require('express'),
var app = express();

app.get('/', function(req, res, next) {
 res.send('Hello, World!'),
});

app.listen(3000);
console.log('Express started on port 3000'),

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

$ npm install --save express

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: "You can also right click on the page, and select Inspect Element."
