How to display on the page the data that was displayed in the console

In a small application made with Express.js, I print text to the console every second and after 4 seconds I stop the text output to the console. I need to return the current date to the page after the input to the console has expired. How can I do this?

var express = require("express");
var app = express();

app.get("/", (req, res) => {
  const utcStr = new Date().toUTCString();
  function outputText() {
    console.log(utcStr);
  }
  const interval = setInterval(outputDate, 100);
  setTimeout(() => {
    clearInterval(interval);
  }, 4000);
  res.send();
});

app.listen(3000);
