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: "We loaded the ngRoute module as a dependent of the routeApp module."

A block of code is set as follows:

'use strict';
app.service('employeeSvc', function () {

  var Employee = function (name, age) {
    this.name = name;
    this.age = age;
  };

Var getEmployees = function () {
    return [
      new Employee("First employee", 56),
      new Employee("Second employee", 44),
      new Employee("Last employee", 32)
    ];
  };

  // Public API
  this.Employee = Employee;
  this.getEmployees = getEmployees;
});

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

<br>
<div>
  <h1>Employee data:</h1>
  <ul>
    <li ng-repeat="employee in employeeData.employees">
      Employee - {{employee.name}} is - {{employee.age}} years old
    </li>
  </ul>
</div>

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

bower install underscore

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: "For other extensions, the Install button is enabled."
