Check if variable is React node or array
提问by ThomasReggi
I'd like to have a condition that states if prop is a React node then just place is as a child within a component, and if it's not, take some action to make it into a component. This way my component will be able to accept this prop as an array of strings, or an array of nodes.
我想要一个条件，如果 prop 是一个 React 节点，那么 place 就作为组件中的一个子节点，如果不是，则采取一些措施使其成为一个组件。这样我的组件将能够接受这个 prop 作为字符串数组或节点数组。
I tried to check if React.PropTypes.nodewould return a boolean and it doesn't.
我试图检查是否React.PropTypes.node会返回一个布尔值，但它不会。
Say I have a module called Listand there's a prop called items. I'd like to be able to pass
假设我有一个名为的模块，List并且有一个名为items. 我希望能够通过
var items = [
"One",
"Two",
"Three"
]
as well as
也
var items = function () {
return (
<li>One</li>
<li>Two</li>
<li>Three</li>
)
}
And within the component have some logic that would detect the difference and if it's a plain array (not an array of nodes) be able to map the items.
并且在组件内有一些逻辑可以检测差异，如果它是一个普通数组（不是节点数组），则能够映射项目。
