    what the Security and JSON Parser

    Security and JSON Parser to understand by below examples 
    // Include http://www.json.org/json.js


    var myObject = myJSONtext.parseJSON();
    eval() can compile and execute any JavaScript program, so there can be security issues (cross-site scripting)
    Use eval() when the source can be trusted
    When security is a concern - the source cannot be trusted -, it is better to use a JSON parser
    A JSON parser will only recognize JSON text and so is much safer Object to Text Conversion
    var myJSONText = myObject.toJSONString();
    You can convert JSON object into JSON text
    JSON does not support cyclic data structure
    Do not give cyclical structures to the JSON stringifier
