/**
 
 ** Exercise 4: What 's the time? **
 
 Why wear a watch when you can check the time, live in your webpage ?

  1. Create a basic HTML file
  2. in the HTML file Include a script tag and link the JavaScript file
  3. Inside the JS file, write a function that adds the current time to the webpage. Make sure it 's written in the HH:MM:ss notation (hour, minute, second). Hint: use `setInterval()` to make sure the time stays current
  4. Have the function execute when it 's loading in the browser

function displayCurrentTime() {
  const currentTime = new Date();
  const n = currentTime.toLocaleTimeString();
  document.body.innerHTML = '<h1>'+ n + '</h1>';
}

setInterval(displayCurrentTime, 1000);
