Shao Yo Huang, what you've submitted does in fact change the value of role to uppercase from then on in your script. If you wanted to utilize this new value place const msg below the change of role.toUpperCase();. You can even drop the let from the second role because you have already added role as a variable and you're simply modifying its value.

let firstName = 'Peter';
let lastName = 'Huang';
let role = 'developer';

role = role.toUpperCase();
const msg = firstName + " " + lastName + " : " + role;
