Note that [refs](/api/reactivity-core.html#ref) returned from `setup` are [automatically shallow unwrapped](/guide/essentials/reactivity-fundamentals.html#deep-reactivity) when accessed in the template so you do not need to use `.value` when accessing them. They are also unwrapped in the same way when accessed on `this`.

`setup()` itself does not have access to the component instance - `this` will have a value of `null` inside `setup()`. You can access Composition-API-exposed values from Options API, but not the other way around.
