What are the best practices for structuring JavaScript code to be independent of DOM structure for flexible form validation?

To make JavaScript code independent of DOM structure for flexible form validation, it is best to use event delegation and selectors to target form elements dynamically. By attaching event listeners to a parent element and checking the target element within the event handler, the code can adapt to changes in the form structure without needing to be updated. This approach allows for more flexible and maintainable form validation code. ```javascript document.addEventListener('submit', function(event) { if (event.target.tagName === 'FORM') { // Perform form validation logic here } }); ```
