    In the context of forms, JavaScript allows direct interaction with the user to dynamically change the form's appearance and content, and to provide immediate and intelligent validation of the user's inputs. JavaScript allows you to instantly add, remove, or modify form fields depending on the user's responses, and to give specific warnings when the user fills out the form improperly or incompletely without requiring a round-trip to the server.
