Conventions

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: "All the code needed to start each chapter can be found in a branch named cp[chapter#]-[sample]."

A block of code is set as follows:

var subtotal = ko.observable(0);
var tax = ko.observable(0.05);
var total = ko.computed(function() {
  var subtotal = parseFloat(self.subtotal()),
  tax = parseFloat(self.tax());
  return subtotal * (1 + tax);
});

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: "You might have noticed in the previous section that when the Contacts page view model communicated with the data service, it wasn't dealing with JSON, but real JavaScript objects."
