### reducedFilter
|
||||
|
||||
Filter an array of objects based on a condition while also filtering out unspecified keys.
|
||||
|
||||
Use `Array.filter()` to filter the array based on the predicate `fn` so that it returns the objects for which the condition returned a truthy value.
|
||||
On the filtered array, use `Array.map()` to return the new object using `Array.reduce()` to filter out the keys which were not supplied as the `keys` argument.
|
||||
|
||||
```js
|
||||
const reducedFilter = (data, keys, fn) =>
|
||||
data.filter(fn).map(el =>
|
||||
keys.reduce((acc, key) => {
|
||||
acc[key] = el[key];
|
||||
return acc;

||||
}, {})
