// Unchanged Magicians: Start with your work from Exercise 40. Call the function make_great() with a copy of the array of magicians’ names. Because the original array will be unchanged, return the new array and store it in a separate array. Call show_magicians() with each array to show that you have one array of the original names and one array with the Great added to each magician’s name.

// Define the original array of magicians
let magicians = ['Harry Houdini', 'David Copperfield', 'Penn Jillette', 'Teller'];

// Define the show_magicians function to print the name of each magician
function show_magicians(magicians) {
  magicians.forEach(function(magician){
    console.log(magician);
  })
}

// Define the make_great function to add "the Great" to each magician's name
function make_great(magicians) {
  let great_magicians = [];
magicians.forEach(function(magician){
    great_magicians.push(magician + ' the Great')
})
  return great_magicians;
}

// Call make_great with a copy of the original array of magicians
let great_magicians = make_great(magicians.slice());

// Call show_magicians with both the original array and the new array of great magicians
console.log("Original magicians:");
show_magicians(magicians);
console.log("\nGreat magicians:");
show_magicians(great_magicians);
