过滤JS/React中的数组

const numbers = [1, 2, 3, 4, 5];

// 过滤出大于2的元素
const filteredNumbers = numbers.filter((number) => number > 2);

console.log(filteredNumbers); // 输出 [3, 4, 5]

import React, { useState } from 'react';

const App = () => {
  const [numbers, setNumbers] = useState([1, 2, 3, 4, 5]);
  const [filteredNumbers, setFilteredNumbers] = useState([]);

  const handleFilter = () => {
    const filtered = numbers.filter((number) => number > 2);
    setFilteredNumbers(filtered);
  };

  return (
    <div>
      <button onClick={handleFilter}>过滤</button>
      <ul>
        {filteredNumbers.map((number) => (
          <li key={number}>{number}</li>
        ))}
      </ul>
    </div>
  );
};

export default App;
