Reactive values function
WebreactiveValues can be used to store objects, to which other expressions can take a dependency. In the example below, a reactiveValues object is initialized with value "No text has been submitted yet.". A separate observer is created to update the reactiveValues object whenever the submit button is pressed. WebThe reactive graph contains one symbol for every input and output, and we connect an input to an output whenever the output accesses the input. This graph tells you that greeting will need to be recomputed whenever name is changed. We’ll often describe this relationship as greeting has a reactive dependency on name.
