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

Visitors using underscore.js can easily convert the address_components array in the geocode response into an object literal:

var obj = _.object( 
    _.map(results[0].address_components, function(c){ 
        return  [c.types[0], c.short_name] 
    })
);

Answer 2

You could use the following function to extract any address component:

function extractFromAdress(components, type){
    for (var i=0; i<components.length; i++)
        for (var j=0; j<components[i].types.length; j++)
            if (components[i].types[j]==type) return components[i].long_name;
    return "";
}

To extract the info you call:

var postCode = extractFromAdress(results[0].address_components, "postal_code");
var street = extractFromAdress(results[0].address_components, "route");
var town = extractFromAdress(results[0].address_components, "locality");
var country = extractFromAdress(results[0].address_components, "country");

etc...

Answer 3

Using lodash

const result = _.chain(json.results[0].address_components)
  .keyBy('types[0]')
  .mapValues('short_name')
  .value()
