Twig array filled with objects to Javascript array

Question

I created a twig array and populated it with objects, and i want to parse that to an javascript array and objects

Twig array:

itm = array:1 [
  0 => array:2 [
    "Test1" => "Testtt1"
    "Test2" => "Testtt2"
  ]
]

I tried to parse it like this but it return and empty array:

var arrAll = [];
 arrAll = {{ itm|json_encode }}

Your question is not clear. Do you have the array available in js script from php ? — Mr Khan

@MrKhan I need to parse that twig array to a javascript but with json_encode() it doesnt work, when i console.log that javascript array it returns me an empty array — Bleron Parduzi

Are you sure you posted a correct dump of the array? I think it cannot be array:8 with only two elements (it should be array:2) — Marcos Labad

@MarcosLabad Yes there were 8 elements in the array but i deleted them for shorter explanation. — Bleron Parduzi

You have to get the raw variable, otherwise it will fail:

 var arrAll = [];
 arrAll = {{ itm|json_encode|raw }}

I tried this but it still is returning an empty array

I can reproduce your array by declaring it this way: $itm = [ [ 'Test1' => 'Testtt1', 'Test2' => 'Testtt2' ] ]; Can you try it? I made the test and it worked perfectly well.

OP's example array does not reflect his/her live data though

@MarcosLabad yes when i make an array and fill it, it does get the value. But I am getting this twig array value from a hook. Eitherway when i dump the twig array it does return the array , but nothing in js.
