||
12 | // |
||
13 | // 1. Enforce API surface and semantic compatibility with 1.9.x branch |
||
14 | // 2. Improve the module's maintainability by reducing the storage |
||
15 | // paths to a single mechanism. |
||
16 | // 3. Use the same single mechanism to support "private" and "user" data. |
||
17 | // 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData) |
||
18 | // 5. Avoid exposing implementation details on user objects (eg. expando properties) |
||
19 | // 6. Provide a clear path for implementation upgrade to WeakMap in 2014 |
