-Sorts elements in the array in ascending order.
+Sorts the elements in an array in ascending order.
 
 ## Syntax
 
 ```sql
-ARRAY_SORT( <array>[, <order>, <nullposition>] )
+ARRAY_SORT(<array>[, 'ASC'|'DESC', 'NULLS FIRST'|'NULLS LAST'])
 ```
 
-| Parameter    | Default     | Description                                                                                                                                    |
-|--------------|-------------|------------------------------------------------------------------------------------------------------------------------------------------------|
-| order        | ASC         | Specifies the sorting order as either ascending (ASC) or descending (DESC).                                                                    |
-| nullposition | NULLS FIRST | Determines the position of NULL values in the sorting result, at the beginning (NULLS FIRST) or at the end (NULLS LAST) of the sorting output. |
+| Parameter     | Default? | Description                                                                                  |
+|---------------|----------|----------------------------------------------------------------------------------------------|
+| `ASC`         | Yes      | Specifies that the sorting order is ascending, arranging elements from smallest to largest.  |
+| `DESC`        | No       | Specifies that the sorting order is descending, arranging elements from largest to smallest. |
+| `NULLS FIRST` | Yes      | Determines that NULL values should appear at the beginning of the sorted output.             |
+| `NULLS LAST`  | No       | Determines that NULL values should appear at the end of the sorted output.                   |
 
 ## Examples
 
+This example shows the array sorted in ascending order by default, with the elements arranged from smallest to largest:
+
 ```sql
 SELECT ARRAY_SORT([1, 4, 3, 2]);
 
-┌──────────────────────────┐
-│ array_sort([1, 4, 3, 2]) │
-├──────────────────────────┤
-│ [1,2,3,4]                │
-└──────────────────────────┘
+-[ RECORD 1 ]-----------------------------------
+array_sort([1, 4, 3, 2]): [1,2,3,4]
+```
+
+This example sorts the array in descending order, arranging the elements from largest to smallest:
+
+```sql
+SELECT ARRAY_SORT([1, 4, 3, 2], 'DESC');
+
+-[ RECORD 1 ]-----------------------------------
+array_sort([1, 4, 3, 2], 'desc'): [4,3,2,1]
+```
+
+This example demonstrates how NULL values are handled in descending order, with NULLs appearing before all non-NULL values:
+
+```sql
+SELECT ARRAY_SORT([1, 4, 3, 2, NULL], 'DESC');
+
+-[ RECORD 1 ]-----------------------------------
+array_sort([1, 4, 3, 2, null], 'desc'): [NULL,4,3,2,1]
+```
+
+This example shows the array sorted in descending order while ensuring that NULL values appear at the end of the sorted output:
+
+```sql
+SELECT ARRAY_SORT([1, 4, 3, 2, NULL], 'DESC', 'NULLS LAST');
+
+-[ RECORD 1 ]-----------------------------------
+array_sort([1, 4, 3, 2, null], 'desc', 'nulls last'): [4,3,2,1,NULL]
 ```
