Wie könnte ich überschreiben eine js-Datei?

Für twig-Template-Datei mache ich&nbsp; {% sw\_extends **‚@parent/block/cms-block-product-listing.html.twig‘** %}

Was soll ich benutzen, um diese Datei:

```
 vendor/shopware/platform/_src_/Administration/Resources/administration/_src_/module/sw-cms/blocks/commerce/product-listing/_index_. **js** 

```

&nbsp;zu vererben?
