Twig : Unset element from array

Question

I have an array of elements composed of key => value for example:

arr = { 156 : 'one', 99 : 'tow' }

I want to remove an element from the array depending on the key. Like doing unset() in php ? Is it possible ?

Answer 1

You can also use the filter pipe like this:

{% set arr = arr | filter((v, k) => k != '99') %}
