Returning MongoDB Items in Meteor

I'm trying to understand how Meteor returns database records. I'm running the following code:

Template.body.helpers({
  items(){
    return Items.find({});
  },
  json(){
    console.log(this.items());
  },
  loggedIn(){
    return Meteor.userId();
  }
});

I'm a little confused as to why this json method doesn't just output and array, or more specifically why the child values don't really seem to just return an array of values.

I can get the values inline html using spacebars, but I'm not sure how to access those values through js. What simple thing am I missing here?

Collection.find() in Meteor returns a cursor, which is a function that can be used by Blaze templates (for example).

Collection.find().fetch() returns an array of objects (i.e. documents).

If you want to parse the database record between multiple helpers or even between templates and routes, why don't you use session variables.

For your example:

Template.body.helpers({
  items(){
    const items = Items.find({});
    Session.set('itemArray', items);
    return items;
  },
  json(){
    console.log(Session.get('itemArray');
  },
  loggedIn(){
    return Meteor.userId();
  }
});

Does this work for you?
