 * `useContext()` call in a component is not affected by providers returned from the *same* component. The corresponding `<Context>` **needs to be *above*** the component doing the `useContext()` call.
 * React **automatically re-renders** all the children that use a particular context starting from the provider that receives a different `value`. The previous and the next values are compared with the [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is) comparison. Skipping re-renders with [`memo`](/reference/react/memo) does not prevent the children receiving fresh context values.
-* If your build system produces duplicates modules in the output (which can happen with symlinks), this can break context. Passing something via context only works if `SomeContext` that you use to provide context and `SomeContext` that you use to read it are ***exactly* the same object**, as determined by a `===` comparison.
