704 Pointsgetting an invalid syntax error
Whenever I run this code
const stringToShout = prompt("What do you want to SHOUT?");
const shout = stringToShout.toUpperCase();
const shoutMessage = <h2>The message to shout is: ${shout}!!</h2>;
document.querySelector('main');
console.log(shoutMessage).innerHTML = shoutMessage;
in a console I get this notifacation:
VM1597:1 Uncaught SyntaxError: Identifier 'stringToShout' has already been declared at <anonymous>:1:1
what is wrong? I followed Professor Guil's code exactly.

231,268 PointsThe particular error message you saw doesn't seem to fit the code shown, but there is another obvious issue:
One video example shows the result using console.log, and another example outputs to the page by updating the innerHTML property of a selected element.
But you can't mix these, since console.log does not return an HTML element.
And for future questions, use Markdown formatting to preserve the code's appearance and retain special symbols.
