如何查找所有具有相同值的对象

const persons = [
  { name: "John", age: 25 },
  { name: "Jane", age: 30 },
  { name: "John", age: 35 },
  { name: "Jack", age: 40 }
];

function findObjectsWithSameValue(objects, key) {
  const result = [];
  const valueMap = new Map();

  for (const obj of objects) {
    const value = obj[key];

    if (valueMap.has(value)) {
      valueMap.get(value).push(obj);
    } else {
      valueMap.set(value, [obj]);
    }
  }

  for (const [value, objArr] of valueMap) {
    if (objArr.length > 1) {
      result.push(objArr);
    }
  }

  return result;
}

const objectsWithSameName = findObjectsWithSameValue(persons, "name");
console.log(objectsWithSameName);
