How can JavaScript functions be modified to accommodate additional button features in PHP forum scripts?

To accommodate additional button features in PHP forum scripts, JavaScript functions can be modified to handle the new functionality. This can involve adding event listeners to the new buttons and creating corresponding functions to execute the desired actions when those buttons are clicked.

<script>
// Example JavaScript function to handle a new button feature
function handleNewButtonFeature() {
  // Add event listener to the new button
  document.getElementById('newButton').addEventListener('click', function() {
    // Execute desired action when the new button is clicked
    console.log('New button clicked');
  });
}
</script>
