Beginners in PHP can ensure they are following proper coding standards and avoiding common mistakes when integrating JavaScript into their projects by using a linter tool like ESLint to catch errors and enforce coding standards. They should also separate JavaScript code into external files and include them using the <script> tag in their PHP files to improve code organization and maintainability.

    &lt;h1&gt;Welcome to my PHP Page&lt;/h1&gt;
