如何在列表中列出项目并在ReactJS中删除重复项？

import React, { useState, useEffect } from 'react';

const ProjectList = () => {
  const [projects, setProjects] = useState([]);

  useEffect(() => {
    // 发送请求或从其他数据源获取项目列表数据
    const fetchData = async () => {
      const response = await fetch('https://api.example.com/projects');
      const data = await response.json();
      setProjects(data);
    };

    fetchData();
  }, []);

  const handleDelete = (projectId) => {
    // 根据项目的唯一标识符或索引删除项目
    setProjects(prevProjects => prevProjects.filter(project => project.id !== projectId));
  };

  return (
    <ul>
      {projects.map(project => (
        <li key={project.id}>
          {project.name}
          <button onClick={() => handleDelete(project.id)}>删除</button>
        </li>
      ))}
    </ul>
  );
};

export default ProjectList;
