How to remove objects in an array by its value?

Question

I am using Node.js and this is my response of my routes.

I want to REMOVE the objects that have the value of "existence":false and output the object that has value of "existence":true"

This is my code so far.

schedule.get('/conference/schedule_participants/:circle/:confUid/:schedId', function(req, res) {
  if(req.schedId){
    getParticipants( req.params, function(contacts){
      results.contacts=contacts;
      res.send('response('+JSON.stringify(results.contacts)+')');
    }); 
  } else{
      res.send('response('+JSON.stringify(results.contacts)+')');
  }
});

You can use Array.prototype.filter:

var filtered = results.contacts.filter(function(c) {
  return c.existence;
});

res.send('response(' +JSON.stringify(filtered) + ')');

@Agent69 that's exactly what I'm doing here ;)

If you don't like the readability, you can change the filter return to return c.existence === true;. But since it's already a boolean, there is absolutely no need for that.

Use Array.prototype.filter()

var filtered = results.contacts.filter(function(contact) {
    return contact.existence;
});
