Q:

How to convert JSON Text to a JavaScript Object ?

Answer

One of the most common use of JSON is to fetch JSON data from a web server (as a file or as an HttpRequest), convert the JSON data to a JavaScript object, and then it uses the data in a web page.


The eval() function can compile and execute any JavaScript. This represents a potential security problem.


It is safer to use a JSON parser to convert a JSON text to a JavaScript object. A JSON parser will recognize only JSON text and will not compile scripts.
