I have been experimenting with a custom module with KnockoutJs on the frontend in M2.

I've created two components: a ProductPackage and a ProductPackagePopop. Functionally, the ProductPackage triggers a modal that renders some details about the package's children.

These two components share quite the same logic which I would like to share between the components. For example, both have a function initTranslation which retrieves the right translations for this store id.

Since I am new to the magento2 Knockout implementation, is there some way to create a base component from which my two components inherit the shared logic? Or a trait like in PHP. I've looked at mixins, but it seems to me it's more fit to extend external is.

define(['uiComponent'], function (Component) {

    return Component.extend({
        store_id: 0,

        initialize: function (config) {
            this.store_id = config.store_id;
            this.initTranslations(config.productPackage);
        },
        initTranslations: function (productPackage) {
          //some logic here
        },
        children: function(){
         // retrieves children
        }


    });
});

I've found this: https://stackoverflow.com/questions/16569810/knockout-viewmodel-base-class-javascript-inheritance , but I find it hard to fit that in the M2 Knockout/RequireJs wrapper.
