在对象数组中按键获取元素

const data = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const targetId = 2;
const result = data.find(item => item.id === targetId);
console.log(result); // 输出: { id: 2, name: 'Bob' }

const data = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const targetNamePrefix = 'A';
const result = data.filter(item => item.name.startsWith(targetNamePrefix));
console.log(result); // 输出: [{ id: 1, name: 'Alice' }]

const data = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const sortedData = data.sort((a, b) => a.id - b.id);
console.log(sortedData[1]); // 输出: { id: 2, name: 'Bob' }
