Example of the Revealing Module Pattern

revealing-module-pattern-example.js

var MyModule = ( function( window, undefined ) {
  
  function myMethod() {
    alert( 'my method' );
  }
  
  function myOtherMethod() {
    alert( 'my other method' );
  }
  
  // explicitly return public methods when this object is instantiated
  return {
    someMethod : myMethod,
    someOtherMethod : myOtherMethod
  };
  
} )( window );

//  example usage
MyModule.myMethod(); // undefined
MyModule.myOtherMethod(); // undefined
MyModule.someMethod(); // alerts "my method"
MyModule.someOtherMethod(); // alerts "my other method"
