title: using variables in underscore.js _.where
body: <p>is it possible to use variables with .where in _.js?</p>
  
  <p>I am making a filtering system that gets an array of objects and filters out the selected objects on click. However, the objects to be filtered are different based on the elements chosen, so I would like to use _.js to filter variables passed to it with _.where</p>
  
  <p>Hardcoded values work perfectly, but when replaced with replica variables, it shoots out a blank array.</p>
  
  <pre><code>var user_filters = user_array;
  var filtered_text;
  $('.allFilters li').click(function () {
      var $this = $(this); 
      var selected_filter = $this.siblings('a').text();
      selected_filter = selected_filter.toLowerCase();
      var filters = $this.attr('data-filter-value');
      filters = '"'+filters+'"';
      selected_filter = selected_filter;
      console.log(selected_filter, filters);
      user_filters = _.where(user_filters, {selected_filter: filters});
      console.log (user_filters);
  });
  </code></pre>
