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 explanations of their meanings.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The union() function concatenates collections, with duplicate values removed."

A block of code is set as follows:

var collection = [ 
    { name: 'Jonathan' },
    { first: 'Janet' },
    { name: 'Kevin' },
    { name: 'Ruby' }
];

if (!_.every(collection, 'name')) {
    return 'Missing name property';
}
// → "Missing name property"

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

npm install -g grunt-cli grunt-contrib-connect
