Compare JSON with JavaScript

Answer

JSON is a subset of the object literal notation of JavaScript 

JSON can be used in the JavaScript language with no muss or fuss

Example: JSON Object
var myJSONObject = {\"bindings\": [ {\"ircEvent\": \"PRIVMSG\", \"method\": \"newURI\", \"regex\": \"^http://.*\"},
{\"ircEvent\": \"PRIVMSG\", \"method\": \"deleteURI\", \"regex\": \"^delete.*\"},
{\"ircEvent\": \"PRIVMSG\", \"method\": \"randomURI\", \"regex\": \"^random.*\"}
]
};

 

 In this example, a JSON JavaScript object is created containing a single member \"bindings\", which contains an array containing three objects, each containing \"ircEvent\", \"method\", and \"regex\" members 


Members can be retrieved using dot or subscript operators myJSONObject.bindings[0].method // \"newURI\"  

Text to Object Conversion in JavaScript code

var myObject = eval(\'(\' + myJSONtext + \')\');

 To convert a JSON text into an JSON object, use the eval() function > eval() invokes the JavaScript compiler . Since JSON is a proper subset of JavaScript, the compiler will correctly parse the text and produce an object structure
