Finds the last element for which the provided function returns a truthy value.
|
|
|
|
- Use `Array.prototype.filter()` to remove elements for which `fn` returns falsy values.
|
|
- Use `Array.prototype.pop()` to get the last element in the filtered array.
|
|
|
|
```js
|
|
const findLast = (arr, fn) => arr.filter(fn).pop();
|
|
```
|
|
|
|
```js
|
|
findLast([1, 2, 3, 4], n => n % 2 === 1); // 3
|
|
```
