console.log(animals.slice(2, 4));
// Expected output: Array ["camel", "duck"]

console.log(animals.slice(1, 5));
// Expected output: Array ["bison", "camel", "duck", "elephant"]

console.log(animals.slice(-2));
// Expected output: Array ["duck", "elephant"]

console.log(animals.slice(2, -1));
// Expected output: Array ["camel", "duck"]

console.log(animals.slice());
