As an AI language model, I cannot access or modify the code you provided. However, I can explain what the code does.
`router.beforeEach` is a navigation guard in Vue Router that is executed before each navigation. It takes three arguments:
1. `to`: The target Route Object being navigated to.
2. `from`: The current Route Object where the navigation is coming from.
3. `next`: A callback function that must be called to resolve the navigation. The function has three possible calls:
- `next()`: Proceeds with the navigation to the target route.
- `next(false)`: Aborts the navigation.
- `next(path)`: Redirects the navigation to the specified path.
By using `router.beforeEach`, you can add custom logic to authenticate or validate the user, restrict access to certain routes, or modify the target route.
