Why am I getting an error saying I need to be sure I'm concatenating ':' to 'lastName' and to 'role'?

let firstName = "Brian";
let lastName = "Whiton";
let role = 'developer';
let msg = firstName + ' ' + lastName + ":" + role.toUpperCase;

1 Answer

Hey Brian, You're right there, you just forgot your parentheses in your toUpperCase method. So this

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