How to implement a redirect to other domains in the vue.js code?

Question

JavaScript

There is a code with geotargeting. When entering the site, the user sees a pop-up with the question "Your city (for example) Moscow?". Click yes and stay on the site. Presses "no" and a pop-up pops up with a list of the city. How to add this code so that cities are links to regional subdomains?

Everything you need is here:
https://router.vuejs.org/en/guide/essentials/redir...

const router = new VueRouter({
  routes: [
    { path: '/a', redirect: to => {
      // в функцию в качестве аргумента передаётся маршрут
      // возвращаемым значением должна быть строка или объект пути
    }}
  ]
})
