print_three_full_names.js

// Here are two name variables:
let some_first_name = "Bob";
let some_last_name = "Joe";
// Here we use them in the name printer function:
print_full_name(some_first_name, some_last_name);
// Or else we can change the first name:
print_full_name("Margaret", some_last_name);
// Or else we can make up both names:
print_full_name("Jane", "Smith");
