My code did not work after I typed my answer into the prompt box on the web page. The alert returned NaN "not a number"

var stringToShout = prompt("What should I shout?"); var shout = stringToShout.toUpperCase(); var shout += "!!!"; alert(shout);

you have already defined 'shout' as a variable, so, when you want to use it you do not need to define it again. so the code should be:

var stringToShout = prompt("What should I shout?");
var shout = stringToShout.toUpperCase(); 
shout += "!!!"; 
alert(shout);

You're declaring the variable shout twice, you need to remove the var keyword before you add the '!!!' to shout.
