# 📖 Rule Details

This rule reports cases where a ref is used incorrectly as an operand.
You must use .value to access the Ref value.

<script>
import { ref } from 'vue'

export default {
  setup () {
    const count = ref(0)
    const ok = ref(true)

    /* ✓ GOOD */
    count.value++
    count.value + 1
    1 + count.value
    var msg = ok.value ? 'yes' : 'no'

    /* ✗ BAD */
    count++
    count + 1
    1 + count
    var msg = ok ? 'yes' : 'no'

    return {
      count
    }
  }
}
</script>
