   A Component has a lifecycle managed by Angular itself. Angular creates it, renders it, creates and renders its children,
   checks it when its data-bound properties change, and destroys it before removing it from the DOM.
   
+  一个组件有一个被Angular本身管理的生命周期。Angular创建它，渲染它，创建和渲染它的子级，在它的数据绑定属性变化时检查它，并在它被从DOM移除前销毁它。
+
   Angular offers **component lifecycle hooks**
   that give us visibility into these key moments and the ability to act when they occur.
   
+  Angular提供**组件生命周期钩子**，提高了这些关键时刻的能见度，并给了我们在它们发生的时候采取行动的能力。
+
   We cover these hooks in this chapter and demonstrate how they work in code.
   
+  我们在本章节覆盖这些钩子，演示它们在代码中是怎么工作的。

   ## Component lifecycle Hooks
+  
+  ##组件生命周期钩子
+  
   Directive and component instances have a lifecycle
   as Angular creates, updates, and destroys them.
   
+  指令和组件实例
+
   Developers can tap into key moments in that lifecycle by implementing
   one or more of the *Lifecycle Hook* interfaces in the Angular `core` library.
