What role does JavaScript play in enhancing the functionality of a dynamic signature preview?

JavaScript plays a crucial role in enhancing the functionality of a dynamic signature preview by allowing for real-time updates and interactive features. By using JavaScript, we can dynamically update the signature preview as the user inputs their information, providing them with a live preview of how their signature will look. Additionally, JavaScript can be used to add interactive elements such as color pickers or font selectors to customize the signature further. 

<script>
// JavaScript code for updating signature preview dynamically
document.getElementById('inputName').addEventListener('input', function() {
  document.getElementById('signaturePreview').textContent = "Hello, " + this.value;
});

// Additional JavaScript code for adding interactive features
document.getElementById('colorPicker').addEventListener('input', function() {
  document.getElementById('signaturePreview').style.color = this.value;
});

document.getElementById('fontSelector').addEventListener('change', function() {
  document.getElementById('signaturePreview').style.fontFamily = this.value;
});
</script>
