Returns all elements in an array except for the first one.
|
|
|
|
- Return `Array.prototype.slice(1)` 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]
|
|
```
