Retrieve index value from JSON

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

JavaScript Object Notation, or JSON, is human-readable text used when transmitting data objects consisting of attribute:value pairs between a server and a web application as an alternative to XML. JSON, while it is originally derived from JavaScript, is a language-independent data format. Code for parsing and generating JSON data is available in many programming languages.
