Some people say that JS loaded with async might be independent of the DOM.&lt;/p&gt; &lt;p&gt;I want to know, how should the JS file actually be written? Is it really completely not supposed to use the DOM at all?&lt;/p&gt; &lt;p&gt;I know the theory of async, but I don’t know what the JS file inside actually looks like. Could someone give an example of JS that works properly with &lt;script async&gt;?&lt;/p&gt; </p> javascript
