Description

The exchange of data over the Internet has been carried out since its inception. Delimiter-separated lists such as CSV and tag-separated languages such as XML are very popular, yet they are considered to be verbose by a section of developers. JSON (JavaScript Object Notation) is a lightweight text-based code to create objects to transfer data over the Internet. It is a data exchange format that is human-readable (like XML, but without the markup around your actual payload) and its syntax is a subset of the JavaScript language that was standardized in 1999. JavaScript and JSON Essentials is a step-by-step guide that will introduce you to JSON and help you understand how the lightweight JSON data format can be used in different ways either to store data locally or to transfer data over the Internet. This book will teach you how to use JSON effectively with JavaScript. This book begins with a brief refresher course on JavaScript before taking you through how JSON data can be transferred via synchronous, asynchronous, and cross-domain asynchronous HTTP calls. JSON is not just about data transfer; this book throws light on the alternate implementations of JSON as well. You will learn the data types that JavaScript uses and how those data types can be used in JSON. You will go through the concepts of how to create, update, parse, and delete a JSON object. You will also look at the different techniques of loading a JSON file onto a web page, how to use jQuery to traverse through an object, and how to perform access operations. You will also go over a few resources that will make debugging JSON quick and easy.

Who is this book for?

This book is a great resource for developers who would like to learn more about JSON and who wish to apply it in their own projects. It will be useful to have some prior knowledge of HTML and JavaScript to help you understand the concepts covered in this book. Some familiarity with a server-side language such as PHP, C#, or Python would also be beneficial, but this is not compulsory.

What you will learn

Learn how to work with real-time JSON

Transfer JSON data via asynchronous calls

Fire cross-domain asynchronous requests

Serialize and transmit data

Very good book for a developer to understand and learn JSON. Very good example provided on each chapter. There ware a few examples though that took time to get to work, hence the reason for 4 stars. I would recommend this to any developer who wants to get started or familiarize himself/ herself with JSON.

Knappe und prägnant gehaltene Einführung ins Thema - nicht mehr und nicht weniger. Die Beispiele bauen auf einander auf und sind gut erklärt.

4 stars because the book is very short in terms of number of pages. It does provide only the essentials of JavaScript and JSON, as stated in the title. I would like to have seen another example with a variety of JSON supported data types used or just more examples or sample files with the html, javascript and JSON. The book did help me understand something of the use of the languages together.

very well presented

JavaScript and JSON Essentials: If you fancy a less verbose data format than CSV or XML, then JSON could be for you. This tutorial will teach you about using JSON with JavaScript for effective local storage or Internet transfers.
