JavaScript: Can this code be refactored into a more functional programming style?

Is it possible to code this code and invalidate the for loop? Using a map and filter?

function listViewFilter(){ // test

  var DateFiltered = containerdata.filter(function (obj){ // remove dates of 010
    return !/010/.test(obj.EventDate); 
  });

  var NameFiltered = [];

  for (var i = 0; i < DateFiltered.length; i++){  // remove EventNames.Name if empty string
    if (DateFiltered[i].EventNames[0].Name == "") continue;
    else NameFiltered.push(DateFiltered[i]);
  }

  Filtered = NameFiltered;
}

Of course your loop for

does nothing but another filter:

function listViewFilter() {
  var DateFiltered = containerdata.filter(function(obj) { // remove dates of 010
    return !/010/.test(obj.EventDate); 
  });
  var NameFiltered = DateFiltered.filter(function(obj, i) { // remove EventNames.Name if empty string
    return obj.EventNames[0].Name != "";
  });
  Filtered = NameFiltered;
}


or shorter

function listViewFilter() {
  Filtered = containerdata.filter(function(obj) {
    return !/010/.test(obj.EventDate) && obj.EventNames[0].Name != "";
  });
}
