Knockout (web framework)  Knockout is a standalone JavaScript implementation of the Model-View-ViewModel pattern with templates. The underlying principles are therefore:   The latter leverages the native event management features of the JavaScript language. These features streamline and simplify the specification of complex relationships between view components, which in turn make the display more responsive and the user experience richer. Knockout was developed and is maintained as an open source project by Steve Sanderson. Knockout includes the following features:   In this example, two text boxes are bound to observable variables on a data model. The "full name" display is bound to a dependent observable, whose value is computed in terms of the observables. When either text box is edited, the "full name" display is automatically updated, with no explicit event handling.  function ViewModel() {  ko.applyBindings(new ViewModel());
