## Error Handling
51+
52+
### Global Error Handlers (🔴)
53+
54+
Global browser error handlers that catch unhandled errors:
55+
56+
- **`window.error`**
57+
- **`window.unhandledrejection`**
58+
59+
**Note:** global errors will be caught using Hawk Catcher.
60+
61+
## Error Test Pages
62+
63+
The playground includes test pages to demonstrate each error catching mechanism:
64+
65+
### Global Error Handlers (🔴)
66+
67+
1. **Runtime Error** (`/errors/runtime-error`)
68+
- Demonstrates synchronous error in event handler
69+
- Caught by `window.error`
70+
71+
2. **Promise Rejection** (`/errors/promise-rejection`)
72+
- Demonstrates unhandled Promise rejection
73+
- Caught by `window.unhandledrejection`
