Oracle JET is not a Javascript framework but it is a Toolkit of Open Source Web Frameworks and oracle glue code to use these frameworks.

Oracle JET is used to display data into Single Page Web Applications but getting data using REST or WebSockets.

Oracle JET supports the Model-View-ViewModel (MVVM) architectural design pattern.

• Model: Used to represent the application data

• View: Used for presentation of Data

• ViewModel: Exposes data from the Model to the view and maintains the application's state.

  

Oracle JET uses cordova plugin to render HTML WebPages into IOS and Android devices using native WebViewer.
