Vue 3.0 Discards Class-Based API for Reusable Composable Function-Based Approach

Vue 2.0 seems to have overwhelmingly positive experience amongst its users. To the extent that there are many fans of the framework. So the current framework must be doing something right.

I personally don't use Vue. Only Angular and some React. But a lot of times in the frontend frameworks change seems to be just for the sake of change. Will be interesting to know what the current Vue users think of this change.
