1. Computed properties
- Computed properties are cached based on their dependencies, while calling methods are always recomputed each time. If you don't need caching, use the method.
- When you have some data that needs to change with other data changes,It's usually better to use computed properties instead of imperative watch callbacks.
2. Listening property watch
- This is most useful when you need to perform asynchronous or expensive operations when data changes .
