外观和模块模式之间的区别

Question

我正在阅读这篇文章，我对facade和module pattern之间的差异感到困惑。

https://carldanley.com/js-facade-pattern/

var MyModule = ( function( window, undefined ) {

  // revealing module pattern ftw
  function MyModule() {

    function someMethod() {
      alert( 'some method' );
    }

    function someOtherMethod() {
      alert( 'some other method' );
    }

    // expose publicly available methods
    return {

      // in our normal revealing module pattern, we'd do the following:
      someMethod : someMethod,

      // in the facade pattern, we mask the internals so no one has direct access by doing this:
      someMethod : function() {
        someMethod();
      }

    };

  }

} )( window );

我们实际上调用同一个私有函数的方式。门面提供的big deal是什么？。
