JavaScript JavaScript Basics Working with Strings Combine and Manipulate Strings

I'm having trouble with this last part of the task. I can't figure out how to get the .toUpperCase function to work.

app.js
let firstName = "Jon";
let lastName = "Adams";
let role = "developer";

let word = role.toUpperCase();

var msg = firstName + " " + lastName + " : " + role;

I am not able to get this to work.

let firstName = "Corey"; let lastName = "Draper"; let role = "developer";

let role = role.toUpperCase();

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

You can't declare (using "let") the same variable twice.

You are using the ".toUpperCase" method correctly, but you are assigning the result to a new variable named "word", and "word" is not being used to create "msg".

Just substitute "word" for "role" in the final statement to pass the challenge.

Thanks!

I have tried var and const still nothing. I have been stuck on this all day.

Corey Draper — you probably have a different issue. Start a fresh question where you can show your own code.

I finally figured it out. It was something simple. Thank you for replying.
