function find(obj, item) {
    for(var key in obj) {                                   // for each key in obj (obj is either an object or an array)
        if(obj[key] && typeof obj[key] === "object") {      // if the current property (value of obj[key]) is also an object/array
            var result = find(obj[key], item);              // try finding item in that object
            if(result) {                                    // if we find it
                result.unshift(key);                        // we shift the current key to the path array (result will be an array of keys)
                return result;                              // and we return it to our caller
            }
        } else if(obj[key] === item) {                      // otherwise (if obj[key] is not an object or array) we check if it is the item we're looking for
            return [key];                                   // if it is then we return the path array (this is where the path array get constructed)
        }
    }
}

var myObj = [{"name":"group1","children":[{"name":"group2","children":[{"name":"item0"}]}]},{"name":"item1"},{"name":"needleGroup","children":[{"name":"needleNestedGroup","children":[{"name":"item3"},{"name":"needleNestedDeeperGroup","children":[{"name":"needle"}]}]}]}];

find(myObj, "needle")
// outputs: ["2","children","0","children","1","children","0","name"]
