title: Meteor: ReactiveVar vs ReactiveDict
body: <p>I understand that the difference between using ReactiveVar and Session variables is, at the basic level, a matter of local vs global variables. ReactiveDict is like a local Session object.</p>
  
  <p>But why use ReactiveDict at all if you're already using ReactiveVar? ReactiveDict doesn't seem to have any advantages over ReactiveVar</p>
