The JavaScript UI Language (JUL) is a configuration and instantiation module for the JavaScript frameworks. It can be used with any framework that accepts a configuration object as a constructor parameter, or with a custom factory for the other frameworks. It parses a tree of configuration objects and creates the run-time components in the expected order and membership. For most uses, after this step, you will have your application's user interface up and running. It implements programming by configuration for event-driven UI JavaScript frameworks; top-down and bottom-up creation of the component tree; and conversion of a DOM XML document into a configuration tree. It supports configuration inheritance and tparser meta-information inside a configuration node. It has fully configurable parsing and the ability to map node IDs as component instances. It supports serialization of the configuration tree to JavaScript or JSON source code.
