Answer 1

If you just want to reset your reactive data you can just do it like this. I have written different approach.

1. This if your only using the index 0, you can just reset the index zero like this.

watch(() => record.value.type, () => {

  state[0] = {value: '', weight: ''};
})

2. If you want to reset every item inside you state:

watch(() => record.value.type, () => {
  state.forEach((item, index) => {
    state[index] = {value: '', weight: ''};
  })
})

3. If you want to reset everything, and start from the very start:

watch(() => record.value.type, () => {
  state.length = 0; // empty the array
  state[0] = {value: '', weight: ''} // add initial value
})
