比较两个JavaScript对象数组并删除常用数组对象(Comparing two JavaScript Arrays of Objects and removing common Array Objects)

var a = [
  [
    {
      id: "AAA"
    },
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "DDD"
    }
  ]
];
var b = [
  [
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "CCC"
    },
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "AAA"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "CCC"
    },
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "AAA"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "BBB"
    }
  ]
];

function remove_duplicates(a, b) {
    for (var i = 0, len = a.length; i < len; i++) {
        for (var j = 0, len = b.length; j < len; j++) {
            if (a[i].name == b[j].name) {
                b.splice(j, 1);
            }
        }
    }

    console.log(a);
    console.log(b);

}

console.log(a);
console.log(b);

remove_duplicates(a,b);
 
 我已经尝试了过滤器并减少了它们，但是它们以期望的结果来到了，我发现了一个类似的结构，但是我得到了一个不同的结构 
 
 从JavaScript或下划线寻求可能的解决方案 
 
 预期结果： [[{"id":"BBB"}],[{"id":"CCC"},{"id":"BBB"}],[{"id":"AAA"}],[‌​{"id":"DDD"}],[{"id"‌​:"CCC"},{"id":"DDD"}‌​]] 

var a = [
  [
    {
      id: "AAA"
    },
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "DDD"
    }
  ]
];
var b = [
  [
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "CCC"
    },
    {
      id: "BBB"
    }
  ],
  [
    {
      id: "AAA"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "CCC"
    },
    {
      id: "DDD"
    }
  ],
  [
    {
      id: "AAA"
    }
  ],
  [
    {
      id: "AAA"
    },
    {
      id: "BBB"
    }
  ]
];

function remove_duplicates(a, b) {
    for (var i = 0, len = a.length; i < len; i++) {
        for (var j = 0, len = b.length; j < len; j++) {
            if (a[i].name == b[j].name) {
                b.splice(j, 1);
            }
        }
    }

    console.log(a);
    console.log(b);

}

console.log(a);
console.log(b);

remove_duplicates(a,b);
 
I have tried the filter and reduce but they are coming with desired result I found a similar one but the one I have got little different structure
 
seeking for possible solution from JavaScript or underscore
 
expected result: [[{"id":"BBB"}],[{"id":"CCC"},{"id":"BBB"}],[{"id":"AAA"}],[‌​{"id":"DDD"}],[{"id"‌​:"CCC"},{"id":"DDD"}‌​]]
