Programs based on these concepts are called reactive, after Alan Kay's Reactive Engine [Kay69]. A well-designed reactive program maintains an internal model that is kept consistent with an end user model. The end user's model is created and modified by direct manipulation, using an input device such as a mouse to alter a visual representation
