Oh, so useContext is like the superhero for managing global state in React, especially when things get super nested. I'm already feeling the pain of prop drilling, so this sounds like a much-needed solution.
Okay, so they're showing how to literally wrap the app with the context provider. That's a clear visual of how it starts to make the state accessible everywhere within that scope. Makes sense how that bypasses the manual passing.
Right, they're creating a new variable to actually use the context value. It’s cool how you just pass the context object into `useContext` to grab the data. I'm curious to see how this looks when it's not just a simple value.

The video begins by introducing the `useContext` hook as a solution for managing global state in React applications, emphasizing its role in sharing data across deeply nested components [0:00]. The speaker illustrates a common problem before `useContext`: the need to pass state through multiple intermediate components, often referred to as "prop drilling." To demonstrate this, the initial setup shows how data would be passed down manually [0:20].
