            Testing done. Please, rucha174, don't forget to add information about behavior for range like [-2 to 1] or [-1 to 1] (see an example) in documentation.

            SET @json= '[ 11, 22 , 33]';
            		 
            SELECT JSON_EXTRACT(@json, '$[-2 to 1]');
            		 
            SELECT JSON_EXTRACT(@json, '$[-1 to 1]');
