You can make it stronger

const checkProxyList = [
  ["http://localhost:7890", "Clash"],
  ["http://localhost:10809", "V2ray"],
  ["http://localhost:1080", "Shadowsocks"],
  // ...
];

const checkProxy = ([proxy, proxyName = ""]) => {
  console.log(`Check ${proxyName} at ${proxy}`);
  return fetch(proxy).then(() => [proxy, proxyName]);
};

Promise.race(checkProxyList.map(checkProxy)).then(([proxy, proxyName]) => {
  console.log(`${proxyName} proxy detected`);
  HttpService.proxy = proxy;
}, () => ({}));
