按公共属性过滤对象数组

// 示例对象数组
const data = [
  { id: 1, name: 'Alice', age: 25 },
  { id: 2, name: 'Bob', age: 30 },
  { id: 3, name: 'Charlie', age: 25 },
  { id: 4, name: 'David', age: 35 }
];

// 基于单一属性的过滤
const filteredByAge = data.filter(item => item.age === 25);
console.log(filteredByAge);

// 基于多个属性的过滤
const filteredByNameAndAge = data.filter(item => item.name === 'Alice' && item.age === 25);
console.log(filteredByNameAndAge);

// 基于复杂逻辑的过滤
const filteredByComplexLogic = data.filter(item => item.age > 25 || item.name.startsWith('C'));
console.log(filteredByComplexLogic);

// 检查过滤条件
const filteredByAge = data.filter(item => item.age === 20); // 条件错误，应该改为 item.age === 25

// 检查数据源
if (data.length === 0) {
  console.log('数据源为空');
} else {
  const filteredByAge = data.filter(item => item.age === 25);
  console.log(filteredByAge);
}
