function App() {
    const [title, setTitle] = useState("");
    const [des, setDes] = useState("");
    const [notes, setNotes] = useState(data);
    const [count, setCount] = useState(4);
 
    function remove(id) {
        setNotes(notes.filter((e) => e.key !== id));
    }
 
    function handle() {
        if (!title || !des) {
            window.alert("Incomplete input");
            return;
        }
        setNotes([...notes, { key: count, title: title, des: des }]);
        setCount(count + 1);
        setTitle("");
        setDes("");
        console.log(notes);
    }
 
    return (
        <div className="App">
            <div className="card">
                <div className="head">
                    <h1>React notes</h1>

                            <div style={{ width: "90%" }}>
                                <h4>Title: {e.title}</h4>
                                <p>Note: {e.des}</p>
