- Implementation Summary
-
- 1. Enforce API surface and semantic compatibility with 1.9.x branch
- 2. Improve the module's maintainability by reducing the storage
- paths to a single mechanism.
- 3. Use the same single mechanism to support "private" and "user" data.
- 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
- 5. Avoid exposing implementation details on user objects (eg. expando properties)
- 6. Provide a clear path for implementation upgrade to WeakMap in 2014
