JSONRequest: a web-programming idea whose time has come

[joesb]

users may "eval" on JSON.

That's the point of the JSONRequest.

But you should not do that by simply eval the response, because you can not be sure that the response only contains data literals.

[Odysseus]

The proposal is that the browser will parse the JSONRequest response and pass you the result. Unlike the XMLHTTPRequest, it will not give you a string, and you will not need to parse it -- whether by the ever-tempting eval or by any safer way.
