React中的useState是同步还是异步的？

import React, { FC, PropsWithChildren, useState } from 'react';

type ITest = {};
const Test: FC<PropsWithChildren<ITest>> = (props) => {
  const [count, setCount] = useState(0);
  const handlePlus = () => {
    setCount(count + 1);
    console.log('count:', count); //<- how count
    setCount(count + 1);
  };
  return (
    <div>
      count:{count}
      <hr />
      <button onClick={handlePlus}>+1</button>
    </div>
  );
};

export default Test;
