In the first code challenge I just noticed the html output of the task. What about console.log('Hello, World!'); code?

What the console.log('Hello, World!'); code in the app.js script is used for? I coundn't see any output from this code snip.

    <p>This is a webpage from inside a code challenge</p>
    <script src="js/app.js"></script>
  </body>
</html>
app.js 
console.log('Hello, World!');

It writes 'Hello world' in the console. To view this right click the page and press inspect and then hit console on the top navigation bar. It should be printed in there.

Hi there,

That line of code will log "Hello, World!" to the console. It will not be seen on the site, but if you open the Developer Tools in the browser, inside the console you will see Hello, World!.

Hope that helps. :) :dizzy:
