Code has been changed to pseudocode, but intent is still there. Original code is using Underscore, fmap from drboolean's typeclasses library and autocurry from wu.js. Original code gets a list of filter commands and a list of products. Filter views are rendered only if products have properties matching filtercommand field names.

var lookupExecute = function( products, processCommands) {
            this.commandArray = processCommands;
            this.lookupArray = products;
        };

// unwrapped values in functor, apply given function over each command object that has lookup items that meet the condition
  lookupExecute.prototype.fmap = function(fn) {
      var self = this,
          mappedResults = map(this.commandArray, function(command) {
            var matchedItems = self.lookupArray.filter(function(item) {
                return item.has(command.FieldName);
            });
            
            return isEmpty(matchedItems) ? command : fn(command);
      });
      // wrap the values back up. 
      return new lookupExecute(this.lookupArray, this.commandArray);
  };
  
  // array is needed in the method
  var executeCommand = function(arry, command) {
    //code that executes command
    
    return command;
  }.autoCurry();
  
  // possible use: render a view using items in collection, only if fieldname of command matches some items
  fmap(executeCommand(prodTypeCollection), new lookupExecute(prodTypeCollection, filterViewCmdArray));
