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

Question

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?

Answer 1

I have an array from twig named filters, this single line did the job

const filters = JSON.parse('{{ filters | json_encode | raw }}');
