Functions

reverse()

Reverse the elements of an array or characters in a string.

reverse(mixed $anyArray) : string

This helper wraps the ArangoDB AQL function REVERSE(expression) which can reverse both arrays and strings. For arrays, it reverses the order of elements. For strings, it reverses the order of characters.

Example AQL usage:

REVERSE([1, 2, 3])          // returns [3, 2, 1]
REVERSE("hello")            // returns "olleh"
REVERSE(doc.items)          // reverses the order of items
Parameters
$anyArray : mixed

Array or string expression to reverse.
