+     * - Array value:
+     *     - if empty then print [] without indent and line break
+     *     - if the array contains no object value, empty array or some other value types,
+     *       and all the values fit on one lines, then print the array on a single line.
+     *     - otherwise, it the values do not fit on one line, or the array contains
+     *       object or non empty array, then print one value per line.
