如何检查一个对象属性是否也存在于另一个对象属性中？

function hasCommonProperties(obj1, obj2) {
  for (let key in obj1) {
    if (obj1.hasOwnProperty(key) && obj2.hasOwnProperty(key)) {
      return true;
    }
  }
  return false;
}

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };

console.log(hasCommonProperties(obj1, obj2)); // 输出: true

function hasCommonProperties(obj1, obj2) {
  const keys1 = Object.keys(obj1);
  return keys1.some(key => obj2.hasOwnProperty(key));
}

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };

console.log(hasCommonProperties(obj1, obj2)); // 输出: true

function hasCommonProperties(obj1, obj2) {
  const set1 = new Set(Object.keys(obj1));
  const set2 = new Set(Object.keys(obj2));
  return [...set1].some(key => set2.has(key));
}

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };

console.log(hasCommonProperties(obj1, obj2)); // 输出: true
