app.js
let firstName = 'Eduardo';
let lastName = 'Guevara';
let role = 'developer';
let msg = firstName + ' ' + lastName + ': ' + role;
let msg = firstName + ' ' + lastName + ': ' + role.toUpperCase();

Conceptually, you might expect this to work since the 2nd assignment of "msg" overwrites the value from the first one. But a variable can only be declared one time, so the 2nd declaration causes an error.

You could fix this by removing the final "let", but removing the first declaration/assignment entirely is a better solution since it is redundant anyway. Either way you'll pass the challenge.
