Hi nassim berkoun

The problem in your code is, that you declared the variable role twice - once with the keyword let, a second time as a constant. In addition, you're trying to uppercase a variable word inside the constant declaration, which doesn't exist.

To fix that, you just need to switch the first role with word and it should work:

let firstName = "NB";
let lastName = "berk";
let word = 'developer';
const role = word.toUpperCase('role');
const msg = firstName + " " + lastName + ':' + role + ".";
