what is wrong with my .toUpperCase code?

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

There's a few issues here:

  • the parentheses on the last line are unbalanced
  • you can't declare the same variable twice
  • the challenge wants the msg to contain an uppercased role, but not change the role variable
  • there should be a colon and a space between the name and role
  • there should not be a period at the end
