### Last of list ### Last of list
Use `arr.slice(-1)[0]` to get the last element of the given array. Use `arr.length - 1` to compute index of the last element of the given array and returning it.
```js ```js
const last = arr => arr.slice(-1)[0]; const last = arr => arr[arr.length - 1];
// last([1,2,3]) -> 3 // last([1,2,3]) -> 3
``` ```
