本文详细介绍了组件生命周期的三个阶段：初始化(initialization)、更新(update)和销毁(destruction)，并提供了每个阶段涉及的关键步骤和方法，如预初始化(preinitialize)、创建子元素(createChildren)、属性提交(commitProperties)等。
组件生命周期包括三步：initialization, update, destruction.
过程方法见下表总结：| Life Cycle Procedure | |||
| initialization | construction | ||
| attachment(be added to the display list and it has a parent) | |||
| initialization | dispatches the preinitialize event | ||
| createChildren() | |||
| dispatches the initialize event | |||
| goes throught a full invalidation & validation ( This step occurs both the here and during the update phase) | commitProperites() | ||
| measure() | |||
| updateDisplayList() | |||
| update | Waiting for update request | ||
| Update request | |||
| Invalidation | |||
| Validation | |||
| destruction | Be removed from this display list no longer referenced anywhere |
