Vue · Senior · Question 44 of 75

What is the difference between `$subscribe` and a `watch` on store state?

✓Correct answer: $subscribe fires once per $patch (not per property) and receives mutation info; it can be detached from the component with { detached: true }
2They are identical
3$subscribe only works in devtools

Explanation

Subscriptions added inside a component are removed when it unmounts unless detached is set. $onAction is the equivalent for actions.
