I have added a space between 'firstname' and 'lastName' but why it shows that my answer is wrong?

app.js 
let firstName = "Vincent";
let lastName = "Cheung";
let role = "developer";
let msg = "firstName " + "lastName:" + "developer."

I can't see the challenge but it seems to be a confusing one. But in your case, the msg variable is currently this, "firstName lastName: developer". You have to remove the quotes from the variable names in order to use the actual variable value.

notice have I have to also add any other characters, like the space, semicolon & space, and period at the end, that I want in the final string

let msg = firstName + " " + lastName + ": " + role + "." // result in "Vincent Cheung: developer.

Another way is to use string interpolation. This to me is easier because anything inside the ${} will be evaluated to whatever the variable value is. Everything else is just literally whatever character you use. 

let msg = `${firstName} ${lastName}: ${role}.` // result in "Vincent Cheung: developer.

Hope this helps
