What are the best practices for organizing JavaScript code in a separate file instead of embedding it in HTML for PHP applications?

When organizing JavaScript code in a separate file for PHP applications, it is best practice to create a separate .js file for your JavaScript code and link it to your HTML using the <script> tag. This helps to keep your code clean, organized, and maintainable. To implement this, create a new JavaScript file, move your JavaScript code into it, and then link it to your PHP file using the <script> tag. 

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP Application&lt;/title&gt;
    &lt;script src=&quot;script.js&quot;&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Hello World!&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;
