key
counter
<button :key="counter" @click="increase">
Can you explain why adding a key solves the problem?
Vue uses keys for deterministic re-evaluation. It's use case is typically for loops, but a key can be used on any component/element. When a key changes, that forces Vue to do a re-evaluation.
Nope, additing key on the button would not make any difference
