What improvements can be made to the JavaScript code to populate a dropdown menu based on user selection from the list?

The issue with populating a dropdown menu based on user selection from a list can be solved by utilizing JavaScript to dynamically update the options in the dropdown based on the user's selection. This can be achieved by using event listeners to detect changes in the selected item and then updating the dropdown menu accordingly. ```javascript // Get the select element and the list of options const selectElement = document.getElementById('selectElement'); const optionsList = { option1: ['Option 1.1', 'Option 1.2', 'Option 1.3'], option2: ['Option 2.1', 'Option 2.2', 'Option 2.3'], option3: ['Option 3.1', 'Option 3.2', 'Option 3.3'] }; // Add event listener to detect changes in the selected item selectElement.addEventListener('change', function() { const selectedOption = selectElement.value; // Clear existing options selectElement.innerHTML = ''; // Populate dropdown menu based on user selection optionsList[selectedOption].forEach(option => { const newOption = document.createElement('option'); newOption.text = option; selectElement.add(newOption); }); }); ```
