how to parse using json

Question

how do parse this data string using json parser {"product": ["collection1", "collection2"]}

Answer 1

1. Please try and make complete sentences.
2. This is an object literal not a data string; data string would have to be "{\"product\":[\"collection1\",\"collection2\"]" (it's actually of importance).
3. The method for parsing json strings, i.e. creating JSON objects from data strings, is JSON.parse() in most browsers (except Opera), or $.parseJSON() using jQuery.

Other than that, please elaborate on what you aim to do, so anyone can make their answers more fitting.
