Thank you, but when watch the Map directly, cb will not be called, is it a right behavior?

@LinusBorg

works fine use deep

watch(() => test.test, () => {
    console.log(111)
},{deep:true})

or

watch(test.test, () => {
  console.log(111)
})

works fine use deep

watch(() => test.test, () => {
    console.log(111)
},{deep:true})

or

watch(test.test, () => {
  console.log(111)
})

Thank you. 👍
