[draw_down]

React Context is essentially scoped global props (the scope is some subtree of the overall component tree; the props are global to that subtree, any component in the subtree can elect to consume them). Why it's an important concept is that it keeps you from needing to pass props down the tree from each component to its children. This is important because often times those intermediate components don't have any concern with the stuff being passed down, so they shouldn't be concerned with data that doesn't matter to them.

Another way of passing around ~global stuff is Redux, which many people find cumbersome and difficult to understand. And by "many people" I mean me.
