Retrieve the user's country location using their timezone
Mapping file of timezone names to ISO country codes. A very, very modest extension of the work detailed by this more clever developer here: https://www.techighness.com/post/get-user-country-and-region-on-browser-with-javascript-only/
Usage
const timezones = require('./timezone_countries.json');
const fips = require('./fips_to_iso.json');
const timezoneName = new Intl.DateTimeFormat('en-US').resolvedOptions().timeZone;
let countryIso = timezones[timezoneName];
let countryName = fips.find(obj => obj.ISO === countryIso).Country;
console.log(countryName);The fips_to_iso.json file is a slim mapping file of ISO-, FIPS, and country names. If you would like richer country data that also maps to ISO codes, highly recommend this project: https://github.com/mledoze/countries
