Creates a new array with n elements removed from the right.

• Use Array.prototype.slice() to remove the specified number of elements from the right.
• Omit the last argument, n, to use a default value of 1.

const dropRight = (arr, n = 1) => arr.slice(0, -n);

dropRight([1, 2, 3]); // [1, 2]
dropRight([1, 2, 3], 2); // [1]
dropRight([1, 2, 3], 42); // []
