What happens if we use context without wrapping the component chain in the provider?

If a component is not wrapped in the Context.Provider, it will receive the default value that was set when the context was created.

The provider's job is to override the default values, essentially providing a dependency injection mechanism to the React component tree.

Remember that in React 19, you dont use .provider syntax, you don't need to type .Provider anymore.

In React 18 and older, MyContext was just an object, and you had to access a special property on it called .Provider. In React 19, the MyContext object is the provider component.
