javascriptで多次元配列の重複を削除

１・名前の重複を削除したい
２・名前が重複していた場合、moneyが2000のデータだけ欲しい

process.stdin.resume();
process.stdin.setEncoding('utf8');
var arr = [
    {id:1,name:"花子",money:5000},
    {id:2,name:"江藤",money:4000},
    {id:3,name:"山田",money:3000},
    {id:4,name:"山田",money:2000},
    {id:5,name:"山田",money:8888},
    {id:6,name:"山田",money:9999},
    {id:7,name:"松井",money:2000},
    {id:8,name:"松井",money:2093},
    {id:9,name:"松井",money:2090},
    {id:10,name:"大川",money:1000}
    ];
var check = [];
arr.forEach(function(list) {
    check[list.name] = (list.name in check) ? true : false;
});

var filtered = arr.filter(function (e) {
    return false === check[ e.name ] || true === check[ e.name ] && e.money === 2000;
} );
console.log( filtered );

結果

[
  { id: 1, name: '花子', money: 5000 },
  { id: 2, name: '江藤', money: 4000 },
  { id: 4, name: '山田', money: 2000 },
  { id: 7, name: '松井', money: 2000 },
  { id: 10, name: '大川', money: 1000 }
