Great. It's right there in the sentence you quoted.
Great doesn't the describe the WAY it is supposed to work. I asked HOW like IN WHICH WAY.
Angular2's architecture is split in such a way that the rendering layer is separated from the application code. This allows swapping out the render layer - enables stuff like NativeScript and React Native renderers, server-side universal and running your app in a web-worker, dispatching to the main thread to render.
