What is the correct answer to this question?

almost, let's try role.toUpperCase()

Hi Callie,

You can use the toUpperCase() method right on your role variable, so without the .string inbetween. Next you'll have to move your shout variable up above the string concatenation otherwise it won't be specified when the string code runs. At last change the role in your string to shout. Since the role value will still be lowercase and the uppercase is saved to shout.

let firstName = "a";
let lastName = "b";
let role = 'developer';
let shout = role.toUpperCase();

let msg = firstName + " " + lastName + ": " + shout;

Mei Lee is right, you use just role.toUpperCase(), but you also don't even need to create that new variable of shout. You can just add the .toUpperCase() to the end of the variable 'role' when concatenating in the msg variable:

let firstName = "Callie";
let lastName = "Crownover";
let role = 'developer';
let msg = firstName + " " + lastName + ": " + role.toUpperCase();

what is wrong here? still Bummer feedback!

let firstName = "Rogier"; let lastName= "Bogaards"; let role = 'developer';

let msg = firstName + ' ' + lastName + ':' + role.toUpperCase();
