JavaScript에서 여러 조건을 사용하여 개체 배열을 필터링하는 방법은 무엇입니까?

<code class="javascript">var users = [
    {
        name: 'John',
        email: '[email&#160;protected]',
        age: 25,
        address: 'USA'
    },
    {
        name: 'Tom',
        email: '[email&#160;protected]',
        age: 35,
        address: 'England'
    },
    {
        name: 'Mark',
        email: '[email&#160;protected]',
        age: 28,
        address: 'England'
    }
];</code>

<code class="javascript">var filter = {
  address: 'England',
  name: 'Mark'
};

users = users.filter(function(item) {
  for (var key in filter) {
    if (item[key] === undefined || item[key] != filter[key])
      return false;
  }
  return true;
});</code>
