如何在javascript中检查对象属性数组是否为空

const obj = { prop1: 'value1', prop2: 'value2' };

if (Object.keys(obj).length === 0) {
  console.log('属性数组为空');
} else {
  console.log('属性数组不为空');
}

const obj = { prop1: 'value1', prop2: 'value2' };
let isEmpty = true;

for (let prop in obj) {
  isEmpty = false;
  break;
}

if (isEmpty) {
  console.log('属性数组为空');
} else {
  console.log('属性数组不为空');
}
