Cant print twig array

Question

I have a twig array i get from a hook, when i dump(array) the array it returns this array:

array:1 [
  0 => array:2 [
    "Key1" => "Value1"
    "Key2" => "Value2"
  ]
]

This is how i dump it:

<div> {{ dump(array) }} </div>

But when i try to print this it returns Nothing:

<div> {{ array }} </div>

I also am trying to convert it to a javascript array like this but it returns null:

var test = {{ itm|json_encode() }};
console.log(test);
