   - يمكن لخطاف `()errorCaptured` أن يرجع `false` لمنع الخطأ من الانتشار أكثر. هذا يعني بشكل أساسي "تم التعامل مع هذا الخطأ ويجب تجاهله." سيمنع أي خطافات `()errorCaptured` إضافية أو `app.config.errorHandler` من الاستدعاء لهذا الخطأ.

+  - In components with async `setup()` function (with top-level `await`) Vue **will always** try to render component template, even if `setup()` throwed error. This will likely cause more errors because during render component's template might try to access non-existing properties of failed `setup()` context. When capturing errors in such components, be ready to handle errors from both failed async `setup()` (they will always come first) and failed render process.

+  - <sup class="vt-badge" data-text="SSR only"></sup> Replacing errored child component in parent component deep inside `<Suspense>` will cause hydration mismatches in SSR. Instead, try to separate logic that can possibly throw from child `setup()` into separate function and execute it in the parent component's `setup()`, where you can safely `try/catch` the execution process and make replacement if needed before rendering the actual child component.
