  const indexes = useReduceValue(
    (acc, a) => [...acc, a], // reducer
    [], // initAcc
    index // value
  );
  return (
    <div>

API

More words

• only changed value will trigger reduce to produce new acc
• if you want to treat continuous same values as different values for this hook, you can wrap the value as [value]
