+Converts an array of objects into an array of values corresponding to the specified `key`.

+- Use `Array.prototype.map()` to map the array of objects to the value of `key` for each one.
+
+```js
+const pluck = (arr, key) => arr.map(i => i[key]);
+```
+
+```js
+const simpsons = [
+  { name: 'lisa', age: 8 },
+  { name: 'homer', age: 36 },
+  { name: 'marge', age: 34 },
+  { name: 'bart', age: 10 }
+];
+pluck(simpsons, 'age'); // [8, 36, 34, 10]
+```
