# 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
