通過(guò)將每個(gè)項(xiàng)目列表對(duì)象作為其 React 組件（名為 ProjectsItem）中的 prop 傳遞，然后將其映射到其<li>標(biāo)簽中的每個(gè)項(xiàng)目信息對(duì)象<ul>：最后出錯(cuò)了介紹.js 文件項(xiàng)目列表（對(duì)象）： const [frontEndProjects, setFrontEndProjects] = useState([{    projectInfos: [{ name: "Imobile Shop", href: "" }],    projectInfos: [{ name: "Portfolio template", href: "" }],    projectInfos: [{ name: "Responsive Design Practice", href: "" }],  }]);  const [machineLearningProjects, setMachineLearningProjects] = useState([{ projectInfos: [{ name: "Hazel AI", href: "" }] }]);  const [backEndProjects, setBackEndProjects] = useState([{    projectInfos: [{ name: "My Little Market", href: "" }],    projectInfos: [{ name: "Todo List app", href: "" }],  }]);  const [webScrapingProjects, setWebScrapingProjects] = useState([{    projectInfos: [{ name: "Business list", href: "" }],    projectInfos: [{ name: "Weather Scraper", href: "" }],    projectInfos: [{ name: "Amazon Price Tracker (done deployement soon)", href: "" }],  }]);  const [javaScriptProjects, setJavaScriptProjects] = useState([{    projectInfos: [{ name: "Javascript: Blackjack - Rock Paper Scissors", href: "" }],    projectInfos: [{ name: "Instagram clone ReactJs", href: "" }],    projectInfos: [{ name: "Facebook Messenger clone ReactJs", href: "" }],    projectInfos: [{ name: "Netflix clone ReactJs", href: "" }],    projectInfos: [{ name: "Amazon clone ReactJs", href: "" }],    projectInfos: [{ name: "Tinder clone ReactJs ( Under Dev )", href: "" }],    projectInfos: [{ name: "Youtube clone ReactJs (LIVE DEMO soon)", href: "" }],    projectInfos: [{ name: "Spotify clone ReactJs (LIVE DEMO soon)", href: "" }],  }]);    const [dataScienceProjects, setDataScienceProjects] = useState([{    projectInfos: [{ name: "Process workbook-Edting Excel files", href: "" }],  }]);它總是只顯示一個(gè)項(xiàng)目，或者當(dāng)我像這樣時(shí)它會(huì)引發(fā)錯(cuò)誤project.projectInfos.map 不是一個(gè)函數(shù)當(dāng)我嘗試通過(guò)更改 .map 位置來(lái)修復(fù)它時(shí)，例如project.map((infos) => <li>{infos.projectInfos.name})project.map 不是一個(gè)函數(shù)它也無(wú)法點(diǎn)火projectInfo.map 不是函數(shù)我試圖通過(guò)給出一個(gè)簡(jiǎn)短的聲明來(lái)總結(jié)，因?yàn)樵谖铱磥?lái)錯(cuò)誤是在 Map() 中。欣賞有關(guān)代碼和改進(jìn)技巧的提示
