### findLast
|
|
|
|
Returns the last element for which the provided function returns a truthy value.
|
|
|
|
Use `Array.filter()` to remove elements for which `fn` returns falsey values, `Array.slice(-1)` to get the last one.
|
|
|
|
```js
|
|
const findLast = (arr, fn) => arr.filter(fn).slice(-1);
|
|
```
|
|
|
|
```js
|
|
findLast([1, 2, 3, 4], n => n % 2 === 1); // 3
|
|
```
