如何从Array中获取数据中的id？

const array = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { name: 'Bob' }
];

const ids = [];
for (let i = 0; i < array.length; i++) {
  if (array[i].hasOwnProperty('id')) {
    ids.push(array[i].id);
  }
}

console.log(ids);  // 输出: [1, 2]

const array = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { name: 'Bob' }
];

const ids = array
  .filter(item => item.hasOwnProperty('id'))
  .map(item => item.id);

console.log(ids);  // 输出: [1, 2]

const array = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { name: 'Bob' }
];

const ids = array
  .filter(({ id }) => id !== undefined)
  .map(({ id }) => id);

console.log(ids);  // 输出: [1, 2]
