I've been trying different ways to get this right and your answer worked for me. This tells me that the JavaScript Basics course need updating.

You can use the method .toUpperCase() in the string concatenation

const msg = firstName + " " + lastName + ":" +  role.toUpperCase() + "."; 

or you can use the new ES syntax and type it like that which is far more readable

let msg = `${firstName} ${lastName}: ${role.toUpperCase()}`;

so I typed this
let letters = role.toUpperCase(); and its giving me the error "Bummer: Use the .toUpperCase() method to convert the role string to all upper-case."

what am I doing wrong?

const msg = firstName + " " + lastName + ":" +  role.toUpperCase() + "."; 

this is the answer and it has been aswered in the same thread you add .toUpperCase() to the role variable.

let msg = `${firstName} ${lastName}: ${role.toUpperCase()}`;

Try to use the ES syntax with the string interiorlation. Well at least it worked for me) The challenge probably wants to use the new Syntax

It is so weird instead of typing the answer like : const msg = firstName + " " + lastName + ":" + role.toUpperCase() + "."; the system only accept : const msg = ${firstName} ${lastName}: ${role.toUpperCase()};

But at this point, we don't know the answer the system accept.

so as was going over this again ,.. this is what I thought the answer would be, as it made sense with what we had learnt so far .. .. let msg = firstName + " " + lastName + ":" + role.toUpperCase() + "."; but alas this is the correct answer, let msg = ${firstName} ${lastName}: ${role.toUpperCase()}; and I am feeling abit lost now .. .

Hey, this is just a new way of string concatenation or string interpolation in other words. The handy part of the new method you don't need bunch of + pluses as it'll contact anyways and even create space when you leave some blank space. But you need also backticks to begin and to close

let firstName = "Tadjiev"; let lastName = "Ruslan"; let role = 'developer';

This is the answer to what you're asking?

Dimitar Dimitrov, you so helpful, The code is working, thank you so much!

pfff posted this:

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

still a "Bummer" feedback. what am i doing wrong here?

Hello, This is what worked for me, hope it helps. Blessings. https://imgur.com/a/NCotEG4

Tadjiev is correct. The course doesn’t tell you but, you need to use the new syntax using the ` , $ and {} instead of single quotes. View his answer. Worked for me as well. Thanks Tadjiev!

This is a huge reason why I think people quit this program. It seems like the quizzes don't align with what we just learned in the other videos which leads into a crapload of time wasted and major frustration. The hint is absolutely crap and confusing, Why would you name something "Shout" then not show the code which it refers to so that we can make sense of it and use the code in a similar fashion to answer this question directly. Instead here I am, confused as heck joining what looks like a lot of people frustrated over the exact same thing.
