如何在JavaScript中比较两个对象数组并删除重复项？

function compareAndRemoveDuplicates(arr1, arr2) {
  var result = [];

  arr1.forEach(function(obj1) {
    if (!arr2.some(function(obj2) {
      return obj1.id === obj2.id; // 根据对象的某个属性进行比较，可根据实际情况修改
    })) {
      result.push(obj1);
    }
  });

  return result;
}

// 示例用法
var arr1 = [{id: 1, name: 'A'}, {id: 2, name: 'B'}, {id: 3, name: 'C'}];
var arr2 = [{id: 2, name: 'B'}, {id: 3, name: 'C'}, {id: 4, name: 'D'}];

var result = compareAndRemoveDuplicates(arr1, arr2);
console.log(result);
