JavaScript JavaScript Basics Working with Strings Combine and Manipulate Strings

Javascript Basics: Working with strings/Combine and manipulate strings exercise. (I’m STUCK).

I’m stuck on this exercise. The question is:

Challenge Task 2 of 3 Below role, create a new variable named msg that combines the firstName, lastName and role variables to create a string like “Carlos Salgado: developer”.

My code is as follows: 

let firstName = " FirstName";
let lastName = "LastName" + ":";
let role = " developer";
let msg = firstName + " " + lastName + role;

My result is:

FirstName LastName: developer.

Which is correct. However the error I get is

Bummer: There should not be a ":" at the end of your lastName string value.

Please advise.
Thank you in advance

your answers is right in the way that you declare the msg variable but the values of the other variables are wrong. The challenge is asking you to create the message "Carlos Salgado: developer" literally that is the answer.

let firstName = " Carlos";
let lastName = "Salgado";
let role = "developer";
let msg = firstName + " " + lastName + ": " + role;

Also when declaring a variable make it more simple if you need to reuse the lastName variable and need only the last name it will also call the colon punctuation, and the role erase the space because you may need it to so keep it clean.

I have tried the solution above, but it doesn't work. What is the exact solution to this?

Below role, create a new variable named msg that combines the firstName, lastName and role variables to create a string like "Carlos Salgado: developer".

HINT: Pay close attention to the spaces in the string.

let firstName = " Carlos"; let lastName = "Salgado"; let role = "developer"; let firstName = "Carlos" + let lastName = "Salgado" + let role = "developer";

Thanks!!

Actually my answer was right but thanks to your hint I just realize that I made a mistake, I typed 

let firstName = " Carlos" //Notice the space at the beginning of the string.

To answer your question about the exact solution you just need to create a variable called msg like so

let firstName = "Carlos";
let lastName = "Salgado";
let role = "developer";
let msg = firstName + " " + lastName + ": " + role;

Then the last part they task you to create the same message but with the role in upper case it should be like this

let firstName = "Carlos";
let lastName = "Salgado";
let role = 'developer';
let msg = `${firstName} ${lastName} : ${role.toUpperCase()}` 
/*this type of string concatenation is called template literals
is a much cleaner way to concatenate string and variables*/

Anyone else think the question itself was not clear? create a string LIKE "Carlos Salgado: developer". should be: create the string "Carlos Salgado: developer"
