how to convert the string to uppercase?

app.js 
let firstName = "Carl";
let lastName = "Odiloff";
let role = 'developer';
let msg = firstName + ' ' + lastName + ': ' + role;
let newForm = role.toUpperCase();

You're using the conversion method properly, but it needs to be done as part of the string being assigned to the "msg" variable. And you won't need to create an additional variable.

The second assignment overwrites the first one. The case conversion should be done as part of just one assignment:

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

Thanks for your reply Steve, I appreciate it. However, I tried what you advised me but it did not work, I tried everything, but nothing seems to work, I do not know maybe there is a glitch in this system. I will try again later, never give up)

Please show the exact code after your changes, perhaps there's another issue.

Hi Steve,

Here is my code after all changes:

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