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: "We just need to open the SpecRunner.html file in a browser and we should see this output."

A block of code is set as follows:

var peopleWithAwardAge = _.map(people, function(person){
  return {
    name: person.name,
    awardAge: person.awardYear - person.birthYear
  }
});

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

var peopleWithAwardAge = _.map(people, function(person){
  return {
    name: person.name,
    awardAge: person.awardYear - person.birthYear
  }
});

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

npm install -g bower

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: "Executing the following line in a Command Prompt with administrator privileges (opened using the Run as administrator option)."
