+# `toArray()`
+
+The toArray method converts the collection into a plain array.
+If the collection is an object, an array containing the values will be returned.
+
+```js
+const collection = collect([1, 2, 3, 'b', 'c']);
+
+collection.toArray();
+
+// [1, 2, 3, 'b', 'c']
+```
+
+```js
+const collection = collect({
+  name: 'Elon Musk',
+  companies: ['Tesla', 'Space X', 'SolarCity'],
+});
+
+collection.toArray();
+
+// ['Elon Musk', ['Tesla', 'Space X', 'SolarCity']]
+```
