concat Method

Now you know that you can concatenate strings with the + operator. As is often the case, in JavaScript, there are more than one ways to do a thing. Here's another way:

"super".concat("user");
// "superuser"

Use the concat method to concatenate as many strings as you like:

"Mr.".concat(" ", "Bilbo", " ", "Baggins", " is", " a", " ", " ", "hobbit");
// Mr. Bilbo Baggins is a hobbit

Of course, you can use variables, too:

let title = "Mr.";
let firstName = "Bilbo";
let lastName = "Baggins";
console.log(title.concat(" " + firstName + " " + lastName + ", hobbit"));
// "Mr. Bilbo Baggins, hobbit"

Your turn. Follow the directions in the code editor and try to pass the tests.
