Problem of serializing javascript object to JSON string

Question

My question is sort of stupid that why

JSON.stringify({"annotation": [{"x":1, "y":2}, {"x":1, "y":2}]})

does not return

{"annotation": [{"x": 1, "y": 2}, {"x": 1, "y": 2}]}

but returns

{"annotation":"[{\"x\": 1, \"y\": 2}, {\"x\": 1, \"y\": 2}]"}

and how can I get the first output?

In which browser are you having this behavior?. If it's a browser with no native JSON support, which library are you using?
I'm using the widely used library from, json.org/json2.js. This seems to be Prototype's conflict.
