The async-tree JavaScript library lets you work with different kinds of hierarchical data as a consistent type of abstract, asynchronous tree. This lets you create applications in plain JavaScript like those possible in the Origami language.
This library is an implementation of the async tree pattern, providing definitions for asynchronous trees backed by standard JavaScript classes like Object and Map and standard browser APIs. The library also includes helper functions for common tree operations.
For an example of a site created with the async-tree library, see the sample async-tree blog site.
