js 数组转对象

const array = [['key1', 'value1'], ['key2', 'value2']];
const obj = array.reduce((accumulator, [key, value]) => {
  accumulator[key] = value;
  return accumulator;
}, {});

console.log(obj); // 输出: { key1: 'value1', key2: 'value2' }

const array = [['key1', 'value1'], ['key2', 'value2']];
const obj = Object.fromEntries(array);

console.log(obj); // 输出: { key1: 'value1', key2: 'value2' }

const array = [['key1', 'value1'], ['key2', 'value2']];
const obj = {};

array.forEach(([key, value]) => {
  obj[key] = value;
});

console.log(obj); // 输出: { key1: 'value1', key2: 'value2' }

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

const obj = array.reduce((accumulator, item) => {
  accumulator[item.id] = item;
  return accumulator;
}, {});

console.log(obj);
// 输出: { '1': { id: 1, name: 'Alice' }, '2': { id: 2, name: 'Bob' } }
