聚合过程中如何过滤掉某些值？

const numbers = [1, 2, 3, 4, 5];
const filteredNumbers = numbers.filter((number) => number > 3);
console.log(filteredNumbers); // 输出 [4, 5]

app.get('/users', (req, res) => {
  const users = [
    { name: 'Alice', age: 25 },
    { name: 'Bob', age: 30 },
    { name: 'Charlie', age: 35 }
  ];
  
  const filteredUsers = users.filter((user) => user.age > 30);
  res.json(filteredUsers);
});

SELECT * FROM users WHERE age > 30;
