Only return zip/postal codes from Google Places AutoComplete Javascript API

It’s been a while, and it took me a while to get Google Maps Places to return only zip codes, so I’ll share a little code snippet so that you can fix it within a quick search!

        const autocomplete = new google.maps.places.Autocomplete(deliveryCheck, {
            types: ['postal_code'],
            fields: ['address_components'],
            componentRestrictions: { country: "us" }
        });
