+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.
+
+```js
+const tail = arr => (arr.length > 1 ? arr.slice(1) : arr);
+```
+
+```js
+tail([1, 2, 3]); // [2, 3]
+tail([1]); // [1]
+```
