Questions tagged [module-pattern]

Module pattern helps to avoid namespace conflicts, and thus is widely use by various third-party scripts, like libraries or banners.

Major drawbacks of using it are: much more difficult debugging and low IDE support. 

var Module = (function ( ) {
      ...

})();
