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
