How do I delete or remove Session variables?

Question

Meteor has a Session that provides a global object on the client that you can use to store an arbitrary set of key-value pairs. Use it to store things like the currently sel

Answer 1

The disadvantage with using delete Session.keys['foo'] is that your template will not hot reload if the session key holds an array. For instance, if you are doing

Template.mytempl.helpers({
    categories: function() {
        return Session.get('srch-categories')
    }
})

and in your template

{{#if categories}}
    {{#each categories}}
        {{this}}
    {{/each}}
{{/if}}

And categories is an array, if you delete the session key, your template will continue to display the last value of categories.
