I am confused on the answer to this question. Can anyone help me out?

app.js 
let firstName = 'James';
let lastName = 'voss';
let role = 'developer';

const message =' firstName +' lastName + ': += role.'

Hey James Voss!

Hope you got the information you needed. I just wanted to pop in and maybe give you some idea on why your answer didn't work originally.

When we assign strings to variables, all we need to do is call the variable to access the string later. Remember, variables are just containers for information. Let's look at your variables:

let firstName = 'James'; // we can now just call firstName and JS will know the content is 'James'
let lastName = 'voss'; // call lastName and JS will know the content is 'voss'
let role = 'developer'; // call role and JS will know the content is 'developer'

So when we build our msg string all we need to do is call the variables and concat some spaces:

let msg = firstName + ' ' + lastName + ': ' + role // output = James voss: developer

I hope this helps. This is a really fundamental part of being a developer and it will only get easier the more you do it! Good luck and happy coding!

My absolute pleasure! It really starts to snowball and soon you'll be doing things like they're second nature!

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