reverse¶

The 'reverse' filter is designed to reverse the order of elements in an array or characters in a string.

Functionality

Arrays: Takes an array as input and returns a new array with the elements in reverse order.
Strings: Takes a string as input and returns a new array where each element is a character of the original string in reverse order.

Syntax

    {{ array_variable | reverse }}

or

    {{ string_variable | reverse }}

Arguments

This filter does not require any arguments.

Code Samples

Example 1: Reversing an Array

    {% assign numbers = [1, 2, 3, 4] %}
    {{ numbers | reverse }}

Output:

[4, 3, 2, 1]

Example 2: Reversing a String (Returning an Array)

    {% assign message = "Hello" %}
    {{ message | reverse }}

Output:

["o","l","l","e","H"]

Example 3: Reversing a String and Joining Back into a String

    {% assign message = "Hello" %}
    {{ message | reverse | join:'' }}

Output:

olleH

Empty Arrays/Strings: If the input array or string is empty, the reverse filter returns an empty array.
Non-Array/String Input: If the input is not an array or string, the reverse filter returns the original input value unchanged.

The reverse filter is useful for manipulating the order of elements in arrays and characters in strings.
For strings, it returns an array of characters by default. If you want a reversed string, you can use the join filter to combine the characters back into a string after reversing.
It does not modify the original array or string; it creates a new one with the reversed order.
