Can you give us an example of your JSON object and what you're trying to achieve with it? – LSW Sep 27 '12 at 6:10

Most browsers contain a native JSON object with a JSON.parse(JSONstring) method for just this. jQuery provides $.getJSON(JSONstring) to return an object from a JSON string in environments that don't natively provide the JSON object.

From there on, getting a useful hashmap depends on the structure of your JSON object. Underscore (and its more performant offshoot, LoDash) contains a lot of useful methods (such as filter) which can help parse, manipulate and retrieve useful data from large objects.
