Best way to convert JSON data to an object in JavaScript?

Question

I am currently using eval in JavaScript to convert JSON data returned from the server into an object.

eval ("myObject="+data);

I've been told that eval is 'evil' and can open up big security problems.

I'm wondering - is using eval to convert JSON data to an object the accepted practice? Or is there a better way?

Now I'm curious if JSON.parse wasn't a thing back then..

The reason eval is considered a bad practice is that user can evaluate anything that is sent from the server. This means if you have comments forum and the user submits some JavaScript code for the comments and you eval on the client side then your website can easily be hijacked.

I like the JQuery-Json plug-in. You can check it out using the following link:

Even John Resig suggests that you use the json2.js library. It's also baked into jquery 1.4.2 as jQuery.parseJSON - if that's the only function you need (rather than parse and stringify). I'd say that jquery-json doesn't really have a place here anymore. Also, we can't assume jQuery on a non jQuery tagged question

If Job Resig suggests to use json2.js then I am moving to json2.js from right now. Thanks!
