In this lesson we'll learn how to render multiple component children from a single route.
Does it has to be "body" and "header" as keywords? What decides the order of the subcomponents being rendered?
No the keys can be whatever you like, sorry if that was not clear.
The order is decided by however you lay your components out, this is covered at 0:25 in the lesson.
const Container = (props) =>
<div>{props.header}{props.body}<Links /></div>
