-除了使用外部传入的数据以外 (通过 `this.props` 访问传入数据), 组件还可以拥有其内部的状态数据 (通过 `this.state` 访问状态数据)。 当组件的状态数据改变时， 组件会调用 `render()` 方法重新渲染。
+In addition to taking input data (accessed via `this.props`), a component can maintain internal state data (accessed via `this.state`). When a component's state data changes, the rendered markup will be updated by re-invoking `render()`.

-使用 `props` 和 `state`, 我们可以创建一个简易的 Todo 应用。 下面这个示例中，我们使用 `state` 来保存现有的待办事项列表及用户的输入。 与此同时，我们也使用了内联的方法添加了事件处理函数，它们将通过事件代理被收集和调用。
+Using `props` and `state`, we can put together a small Todo application. This example uses `state` to track the current list of items as well as the text that the user has entered. Although event handlers appear to be rendered inline, they will be collected and implemented using event delegation.

+Build encapsulated components that manage their own state, then compose them to make complex UIs.
 
-无需再用模版代码，通过使用JavaScript编写的组件你可以更好地传递数据，将应用状态和DOM拆分开来。
