Use `.reduce()` to convert the filtered/picked keys back to a object with the corresponding key:value pair if the key exist in the obj. Use `Array.reduce()` to convert the filtered/picked keys back to a object with the corresponding key:value pair if the key exist in the obj.
```js ```js
const pick = (obj, arr) => arr.reduce((acc, curr) => (curr in obj && (acc[curr] = obj[curr]), acc), {}); const pick = (obj, arr) =>
arr.reduce((acc, curr) => (curr in obj && (acc[curr] = obj[curr]), acc), {});
// const object = { 'a': 1, 'b': '2', 'c': 3 }; // pick({ 'a': 1, 'b': '2', 'c': 3 }, ['a', 'c']) -> { 'a': 1, 'c': 3 }
// pick(object, ['a', 'c']) -> { 'a': 1, 'c': 3 }
