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: "This will start a server on port 9880 keeping runner mode QUIET as you can see in the command prompt after running the command."

A block of code is set as follows:

<script>
YUI().use('test-console','test', function (Y) {
      var testCase = new Y.Test.Case({
        /*
        * Sets up data needed by each test.

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

toCurrencyAmount = rateOfConversion* amount; // rounding off toCurrencyAmount = Number.parseFloat(toCurrencyAmount).toFixed(2);

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

npm install karma –save-dev

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: "Click on the first link Capture This Browser, which will allow JsTestDriver to capture this browser."

Note

Warnings or important notes appear in a box like this.
