[Resolved]Do I need to remove all children for each Layers under the same parent again?

cocos2d-x JavaScript
#1

I have several Layers under the same parent layer, and each layer has its own several nodes.
If I call “removeAllChlidrenWithCleanup(true)” from that parent layer, Do I need to call that function or remove all all children from each layer again ?
Those layer will be re-created the next time players replay the game.

If I won’t call it, is there’s going to be performance or memory issue ?

#2

Like Array in Javascript, when Array instance lose reference pointer, GC will release this Array instance and SubObject of this Array instance.
so don’t worry about memory issue.

Okay, thanks for reply.
