I keep getting this prompt: Bummer: Use the `.toUpperCase()` method to convert the `role` string to all upper-case.

I am using const developer = role.toUpperCase();

app.js 
let firstName = 'JP';
let lastName = 'Castrillon';
let role = 'developer';
const developer = role.toUpperCase();
const msg = firstName + ' ' + lastName + ' : ' + role;

Hi there, Juan Pablo Castrillon! You're doing fantastic! Yes, you converted the role to upper case and then stored it in developer. But then when you're displaying it, you're displaying role which is still lower case.

So where you have:

const msg = firstName + ' ' + lastName + ' : ' + role;

You would need:

const msg = firstName + ' ' + lastName + ' : ' + developer;

Hope this helps! :sparkles:
