[FIXED] How to convert a Twig array into JavaScript array

Issue

I have a Twig array and I want to send it to JavaScript:

<script>
    var packages = {{packages}}
</script>

Error! Array to String Conversion.

How should I do that?

Solution

You may use json_encode twig filter to pass your arrays into javascript:

Twig

{% set packages = [1, 2, 3, 4] %}

<script>
    var packages = {{ packages|json_encode }}
</script>

Output

<script>
    var packages = [1,2,3,4]
</script>
