如果条件为
true
时，
Display
组件将会显示单个子节点，当条件为
false
时，
Display
组
件将会显示其他内容。为了实现这一点，我们创建了
WhenTruthy
和
WhenFalsy
组件，并
将它们作为
Display
组件的子元素。
findChild
函数会使用
React.Children
将子节点转换
成一个数组。可以对该数组进行过滤和定位，并根据组件类型返回一个唯一的子节点
元素。

脚本库
Angular
和
jQuery
这类框架库内置的工具包括数据访问、渲染

、模型化
State
、路由
处理等。换句话说，
React
只是一个简单的创建视图脚本库，因此我们需要将它和其

JavaScript
脚本库搭配使用。如果我们理解了生命周期函数操作流程，那么我们可
以让
React
库和其他
JavaScript
脚本库良好地协同工作。
React
和
jQuery
将
React
和
jQuery
一起搭配使用，往往会遭到社区成员的一致反对。将
jQuery
和
React
集成到一起协作是完全可行的，并且集成过程也是学习
React
或者将遗留
代码迁移到
React
的好机会。不过如果我们没有选择大型的框架库，而是将更小
的脚本库和
React
一起集成后，构造的应用程序性能会更好。此外，使用
jQuery
绕过虚拟

而直接操作
DOM
后，可能会导致一些奇怪的错误。
在本节中，我们将会集成一对不同的 ...
