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