JavaScript JavaScript Basics Working with Strings Combine and Manipulate Strings

what am i doing wrong

let firstName = ('Daniel');
let lastName = ('Corio');
let role = 'developer';
let msg = firstname + " " + lastname ": " + role ".";

1 Answer

The N in firstName and lastName should be capitalized.

Use + to combine the value of lastName and the string ": ".

The example msg does not include a . at the end. If it did, role "." would need to be changed to role + "." Since it does not, role "." should be changed to role
