Making a do while loop on HTML5

i was trying to get my code right when i had to make a do while loop and i tried asking my user the capital of United States and the answer must be “Washington” so i needed to make it perform an action of restricting the user from making more than 3 trials, please anyone there who understand what i’m saying, I’m stalked

What have you tried so far?

Can you put an example in codepen?

<!DOCTYPE html>
<html>
<head>
	<title>Working With Do While Loop</title>
</head>
<body>
<h1>Working With Do While Loop</h1>

<script>
	do{
		var answer = prompt("Capital Of United States?");

	} while (answer != 'Washington');
</script>

</body>
</html>

Okay Randell, thank you so much
