JavaScript JavaScript Basics Working with Strings Combine and Manipulate Strings

Hi, I'm not sure what I'm missing or doing wrong. Can someone advise? Thanks!

my code is attached

app.js
let firstName="Yessenia";
let lastName="Bojorquez";
let role = 'developer';
let role = (role.toUppercase);
let msg = firstName + ' ' + lastName + ': ' + role;

Hi Yessenia,

Your code is almost perfect. I think the first issue you’re running into is two parts. 1) toUpperCase is a method and not a property. You have to invoke it with parens. So it’s toUpperCase(). 2) the “C” in toUpperCase needs to be capitalized. Syntax errors are common for all developers, but toUpperCase() is different from toUppercase.

If you make those changes, you’ll end up getting an error that says something to the extent that the original role variable should not be changed, which means that Treehouse wants you to store ‘developer’ as is in the variable role, while outputting it as ‘DEVELOPER’ only in the string stored in msg.

If you have trouble figuring out that last part, let me know.

Thanks Brandon! That helped out.
