Why ref wouldn't be unwrap when assign to a <ref>.value

[FoundTheWOUT]

ref will unwrapped when assign to a reactive obj, and will also unwrapped when passing it to the first argumrent of a ref.

const obj = reactive({})
const name = ref(1)
const foo = ref()
const bar = ref(name) // unwrapped
obj.foo = name // unwrapped
foo.value = name // not unwrapper
