More efficient way to extract address components

Question

Currenty, I\'m using the following code to get the country, postal code, locality and sub-locality:

var country, postal_code, locality, sublocality;
for (i =         


        

Answer 1

I made function before that extracts a list of values given a list of place types:

const getValue = function(data, types=[]){
/* used by results taken from Geocoder.geocode api */
const values = data.reduce((values, address) => {
    return address.address_components.reduce((values2, component) => {
        if(component.types.reduce((result, type) => result || types.indexOf(type) > -1, false))
            values2.push(component.long_name);
        return values2
    }, []);

    if(buff.length)
        return [...values, ...buff];
    return values;
}, []).filter(
    (value, index, self) => {
        return self.indexOf(value) === index;
    }
);

}
