finally

app.js 
let firstName = "virginia";
let lastName = "chubo";
let role = 'developer';
let msg = firstName + ' ' + lastName + ':' + ' ' + role;
let msg = firstName+ " " + lastName ": " + (msg.toUpperCase());

You're very close... but what's happening here is you're attempting to do the same line again and the variable you're calling toUpperCase() on will convert the entire string to uppercase.

Remove the second line and call toUpperCase() on the variable that only stores the value for the developer part of the string. :)

Hey Jonathan! I'm on the same challenge. When calling toUpperCase() on the variable I get an error saying, "Cannot read property '1' of null".

let firstName = "Gill"; let lastName = "Mercer"; let role = "developer"; const.role = role.toUpperCase(); let msg = firstName + " " + lastName + ": "+ role;
