Conventions

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: "Therefore, once we have the page loaded, we send keystrokes (sendKeys) into the #source input box with the Italian word "Ciao"."

A block of code is set as follows:

variable = produceAValue()
print variable
// some value is output when #produceAValue is finished.

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

> This happens first
> Then the contents are available, [file contents shown]

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 should see You just deployed some Node! displayed."
