Now "each" component is not a TransformComponent subclass any more. Instead, it just becomes a List component with some additional field and method. some works are done in 'willRender' and 'didRender' compnent event.

It is possible to generalize the new solution for "each" component to all TransformComponent, and remove TransformComponent class hierarchy. But I does not get the whole solution for now. The difficult exists in multiple level chained transformation and one baseComponent can be used in different places. Expect more ideas about this.

• minify the removing and reinsert of node as possible

  A B C D -> B C D A, should only removing and reinsert A, because only A's succ is changed

  A B C D -> D A B C, should only removing reinsert D, because only D's succ is changed.

  method:

  record parent and nextNode, and the status of whether they are lived in dom

  Component.alive field

Now There is basically enough Chinese document, which has covered many aspects of domcom. But more English document is required. Hope someone can help to add more English documents. Your contribution are very appreciated and welcomed! Thanks!

The getBaseComponent method was used some time ago, but it was removed in the latest big refactor. Now I think it may be better to add it back, and only removeNode and attachNode when oldBaseComponent != newBaseComponent
