Interface Mapping<Source, Target>

Keeps an array of result objects synchronized with an array of source objects. See Working with arrays.

Mapping provides a [[map]] function that updates its [[results]]. The [[map]] function can be called multiple times and the results will get created, removed and updated accordingly. A Mapping can be used to keep an array of components (objects with a render method) synchronized with an array of data. Instances of Mapping can be created using [[createMapping]].
