                const newKey = (current ? current + '.' + key : key);
                if (value && typeof value === 'object') {
                    recurse(value, newKey);
                } else {
                    res[newKey] = value;
                }
            }
        }
    }
    recurse(obj);
    return res;
}
dotify({'a':{'b1':{'c':1},'b2':{'c':1}}}) //{'a.b1.c':1,'a.b2.c':1}
