I am not understanding what they mean when they say Make sure you're concatenating `: ` to `lastName` and `role`.

app.js 
let firstName = "Jaylen";
let lastName = "Wakefield";
let role = 'developer';
let msg = firstName + ' ' + lastName + ':' + role;

Hey jaylen wakefield 👋

It means you'll want to make sure that the string ": " is being added in between the lastName and role variables. Judging from your snippet it looks like you only got the colon and the space seems to be missing 🙂

let msg = firstName + ' ' + lastName + ': ' + role;

Hope this helps!
