 ## Optimized
 
 ### For modern browsers
 
 ```html
-<script>(function(d,s){
-if(window.Promise&&[].includes&&Object.assign&&window.Map)return;
-var sc=d.getElementsByTagName(s)[0],js=d.createElement(s);
-js.src='https://cdn.polyfill.io/v2/polyfill.min.js';
-sc.parentNode.insertBefore(js, sc);
-}(document,'script'))</script>
+<script>if(!(window.Promise&&[].includes&&Object.assign&&window.Map)){document.write('<script src="https://cdn.polyfill.io/v2/polyfill.min.js"></scr'+'ipt>')}</script>
 ```
 
 This only includes polyfill.io when necessary, skipping it for modern browsers for faster load times.

 This is the same as the previous, but also adds a polyfill for `window.fetch()`. We add a `window.fetch` check and loads the additional `fetch` feature.
