Comment on JQuery 1.4 and Malformed JSON

Could someone tell me why the example given is malformed? I rarely write JSON anymore (except with json_encode in php and simplejson in python).

The malformed example given is:

    {foo: "bar"}

which is missing the quotes around foo so it should be:

    {"foo": "bar"}

Since both of those would have had the same meaning the JSON spec sensibly restricts things so that only one is valid. See http://json.org/ for the (very short and readable) spec.

The reason for outlawing the first syntax is that it isn't a legal javascript literal in the case where the key is a javascript reserved word (if we change 'foo' to 'for' in this example).

Thanks.

The object property is assigned with a name, not a (double-quoted) string. Well-formed JSON would look like this:

    {"foo": "bar"}
