const countries = require("https://ninjahosting.ninjablade.repl.co/jsHosting/script.js");
let n = 0;
while (n < 198) {
  n++;
  setTimeout(()=>{document.getElementById(elementId).value = countries[(n+1)]; }, delay*n);
}

When I run this code, I get this error

"41:19 Uncaught ReferenceError: require is not defined"

That's the fiddle
