Read a lot also on Stack Overflow and here about variable scope global vs local, but i can't find a solution, in my case, access the latitude and longitude variables outside the function:

var latitude = "";
      var longitude = "";
      
      // Find location
      if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
      } else {
      // x.innerHTML = "Geolocation is not supported by this browser.";
      }
      
      function showPosition(position) {
        console.log("Latitude: " + position.coords.latitude + ", Longitude: " + position.coords.longitude);
        var latitude  = position.coords.latitude;
        var longitude = position.coords.longitude;
      }
      console.log(latitude) // no access!

      navigator.geolocation.getCurrentPosition(showPosition);
      
      var mymap = L.map('mapid').setView([latitude, longitude], 15);

Someone can help me out? i hink the problem is a function in a function?
