按数组属性重复数组对象元素

function duplicateArrayObjectsByProperty(arr, property) {
  const result = [];
  
  arr.forEach(obj => {
    const value = obj[property];
    const count = arr.filter(item => item[property] === value).length;
    
    for (let i = 0; i < count; i++) {
      result.push({...obj});
    }
  });
  
  return result;
}

// 示例用法
const originalArray = [
  { name: 'Apple', color: 'Red' },
  { name: 'Banana', color: 'Yellow' },
  { name: 'Orange', color: 'Orange' },
  { name: 'Apple', color: 'Green' }
];

const newArray = duplicateArrayObjectsByProperty(originalArray, 'name');
console.log(newArray);

[
  { name: 'Apple', color: 'Red' },
  { name: 'Apple', color: 'Red' },
  { name: 'Banana', color: 'Yellow' },
  { name: 'Orange', color: 'Orange' },
  { name: 'Apple', color: 'Green' },
  { name: 'Apple', color: 'Green' }
]
