Returns all elements in an array except for the first one.

• Use Array.prototype.slice()to return the array without the first element if Array.prototype.length is more than 1.
• Otherwise, return the whole array.

const tail = arr => (arr.length > 1 ? arr.slice(1) : arr);

tail([1, 2, 3]); // [2, 3]
tail([1]); // [1]
