public final class Context<T>
extends Object

Context is designed to share data that can be considered "global" for a tree of views. In a typical React application, data is passed top-down (parent to child) via inputs, but this can be cumbersome for certain types of inputs (e.g. locale preference, UI theme) that are required by many views within an application. Context provides a way to share values like this between views without having to explicitly pass a input through every level of the tree.
