在这种形式的验证中，是否存在反应18的问题？

Question

在表单验证中，我使用Handel change，问题是它在输入值和状态变化中没有显示单个值，最后在提交时没有显示答案是否是react 18版本的问题.imagehttps://drive.google.com/file/d/1s1uvHR7LrDOh1Ud2_hBzuFXum-MWYBHh/view?usp=sharing

import React, { useEffect, useState } from "react";
export default function App() {
    const [data, setData] = useState({
        name: "",
        password: "",
    });

    function handlechange(e) {
        let { name, value } = e.target;
        return setData({ ...data, [name]: value }), console.log(data);
    }

    const onSubmithandeler = (e) => {
        let names = data.name;
        let passwords = !data.password.match(1);
        if (!names) {
            console.log("invalide name");
        } else if (!passwords) {
            console.log("password invalid");
