Is JSON.parse supported by all major browsers? [duplicate]

Answer 1

I am afraid not. You can however use json2 script written by Douglas Crockford.

Here is what John Resig (creator of jQuery) has to say about it:

JSON2.js - Late last year Crockford quietly released a new version of his JSON API that replaced his existing API. The important difference was that it used a single base object (JSON) instead of extending all native object prototypes (booo!).
