Correct: D
JavaScript is commonly used for form validation to ensure that user inputs are correct and meet specific criteria. It is also frequently utilized for creating dynamic animations that enhance the user experience. JavaScript can dynamically generate content on web pages, providing real-time updates without the need for a page reload. However, JavaScript is not typically used for direct database management, as this task is typically handled by server-side languages like SQL or PHP.
