pop

Removes and returns the last element from an array. Modifies the original array in place.

{% assign last_item = my_array | pop %}
{% log last_item %}

Syntax

{{ array | pop }}

Parameter	Description
array	Array to remove the last element from

Return Value

Returns the removed element. The original array is shortened by one element.

Examples

Pop the last element:

{% assign colors = "red,green,blue" | split: "," %}
{% assign last = colors | pop %}
{% log last %}
{% log colors %}

Output:

blue
["red", "green"]

Process items from the end:

{% assign stack = "first,second,third" | split: "," %}
{% assign item = stack | pop %}
{% log "Processing: " | append: item %}
{% log "Remaining: " | append: stack.size %}

Use with the pop tag for named assignment:

{% pop my_array as last_element %}
{% log last_element %}

Notes

• Modifies the original array — the popped element is removed permanently

• Returns the input unchanged if it is not an array

• There is also a {% pop array as variable %} tag that does the same thing with a clearer syntax
