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: "An instance of this class needs to be passed to the Sort routine of the List<T> instance."

A block of code is set as follows:

    class Employee 
    { 
        public String name {get;set;} 
        public int age {get;set;} 
        public double salary { get; set; } 
    }

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

    return function () { 
      try { 
        return fn.apply(null, args.slice(1)); 
      }

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

npm install rx

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 could simply do this in JSbin by using the Add library option shown in the web editor."

Note

Warnings or important notes appear in a box like this.

Tip
