It's a UI component so we need to get it via uiRegistry and then get the value:


And put 'uiRegistry' as one of the dependencies of my js file. Below are the full code of my js file

], function ($,uiRegistry) {
    'use strict';
    jQuery(document).ready(function () {
       var category_ids=uiRegistry.get('product_form.product_form.product-details.container_category_ids.category_ids').value();
