 The `querySelectorAll` method returns an array-like object called a node list. These data structures are referred to as "Array-like", because they appear as an array, but can not be used with array methods like `map` and `foreach`.

+```javascript
 const nodelist = document.querySelectorAll('div');
 const nodelistToArray = Array.apply(null, nodelist);
