js移除object一个元素

let obj = {
  key1: 'value1',
  key2: 'value2',
  key3: 'value3'
};

delete obj.key2; // 删除key2属性

console.log(obj); // 输出: { key1: 'value1', key3: 'value3' }

let obj = {
  key1: 'value1',
  key2: 'value2',
  key3: 'value3'
};

let { key2, ...newObj } = obj; // 使用解构赋值排除key2

console.log(newObj); // 输出: { key1: 'value1', key3: 'value3' }

let obj = {
  key1: 'value1',
  key2: 'value2',
 **  key3: 'value3'
};

let newObj = Object.keys(obj).reduce((acc, key) => {
  if (key !== 'key2') acc[key] = obj[key];
  return acc;
}, {});

console.log(newObj); // 输出: { key1: 'value1', key3: 'value3' }
