Modifications in all JS frameworks are the same. Some interaction causes an event, that event is caught and changes some data, that data then triggers the render functions which show the new UI. This is often coded with event handlers linked to actions/mutations/reducers in some kind of state management library.

Vue (and some other frameworks) use a reactivity approach where the data is wrapped with a proxy that basically automates all this code. I find it much easier to reason about since it greatly reduces the complexity and you can focus on the actual data changes rather than all the plumbing to change the data.
