var myModule = { myProperty: "someValue", // object literals can contain properties and methods. // e.g we can define a further object for module configuration: myConfig: { useCaching: true, language: "en" }, // a very basic method saySomething: function () { console.log( "Where in the world is Paul Irish today?" ); }, // output a value based on the current configuration reportMyConfig: function () { console.log( "Caching is: " + ( this.myConfig.useCaching ? "enabled" : "disabled") ); }, // override the current configuration updateMyConfig: function( newConfig ) { if ( typeof newConfig === "object" ) { this.myConfig = newConfig; console.log( this.myConfig.language ); } } }; // Outputs: Where in the world is Paul Irish today? myModule.saySomething(); // Outputs: Caching is: enabled myModule.reportMyConfig(); // Outputs: fr myModule.updateMyConfig({ language: "fr", useCaching: false }); // Outputs: Caching is: disabled myModule.reportMyConfig();
