let firstName = "Karunakar"; let lastName = "Patel"; let role = 'developer'; const msg = firstName + " " + lastName + "

I was really stuck on this, I don't know y this is not working.

app.js 
let firstName = "Karunakar";
let lastName = "Patel";
let role = "developer";

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

console.log(msg);
