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: "The g_user global object can be used to retrieve user session information in client scripts."

A block of code is set as follows:

function DemoCallBack(response) { 
//javascript code 
var answer = response.responseXML.documentElement.getAttribute("answer");  
console.log(answer); 
}

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: "Navigate to the bottom of the page and click on the New button in the Database Indexes related list."
