Example

Here is an example to show the basic concept. Commands that simply add two numbers together can easily be merged together thanks to the associative property. 

var AddCommand = function AddCommand(inc) {
  this.$inc = inc;
  Command.call(this, {
    displayName: 'Add ' + inc + ' to the given number',
    func: function (num) { return num + inc; }
  });
};
AddCommand.prototype = Object.create(Command.prototype);

AddCommand.prototype.merge = function (cmd) {
  if (cmd instanceof AddCommand) {
    return new AddCommand(this.$inc + cmd.$inc);
  }
};

var addOneCommand = new AddCommand(1),
    addFiveCommand = new AddCommand(5),
    addSixCommand = addOneCommand.merge(addFiveCommand);
addSixCommand.invoke(10)
  .then(function (result) {
    console.log('is 16? ', result === 16);
  });
