Answer 1

You want to loop through your array like so:

let firstnameList = ["Jan", "Mark", "Doe"];
for (let firstName of firstnameList) {
    //In here you can access the current first name by using the newly created variable firstName
    console.log('Hello ' + firstName);
    // Or
    console.log(`Hello ${firstName}`);
}
