Hi, this question is really challenging me can I get help?

Hello Shima!

There's just a few things that need to be changed to get you passing this challenge. The first thing we can do is delete the bottom line of code and put the .toUpperClass() method into our top msg variable. A few key things to point out:

• The message variable is already defined with let msg so if we wanted to change it in the future all we'd have to do is write the variable name msg. You can't define (aka use let, const, or var) two variables with the same name!
• This code is synchronous which means that it's going to execute one line of code and then continue on to the next. Even if we were to delete the let out of the second message line it still wouldn't work. You'd be telling the code to forget the previous message and instead make the message just the role in upper case.

After deleting the bottom line and adding the method to the msg variable our code should now look like this:

let firstName = "shima";
let lastName = "abdalla";
let role = 'developer';

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

From here we just have to change how we're concatenating the variables. Let's see how our current message compares to the desired one in the challenge:

// current message
shima abdalla:DEVELOPER.  

// desired message
shima abdalla: DEVELOPER

By writing out what we've written and comparing it, we can see that we need to put a space after the colon and delete the period at the end of the message. Once we do that we have our final code:

...

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

Hope this helps!
