JavaScript design mode--constructor

The module mode is a block of code that provides public and private methods, facilitates encapsulation of organization code, and reduces the conflict between variables and function names against other modules.

The module model is varied and I only list the module patterns that are commonly used, or are relatively perfect or have special uses.

1. Revealing module mode with private variable plus "_"

var Module = (function  () {  varfunction  () {    //  Private Stuff  };   var function () {    _privatemethod ();  };     return {    publicmethod:publicmethod  };}) ();

All functions are placed inside the function, and the private function or variable is preceded by "_", and the public method uses the same name as the return object to directly reference the function inside. This is a very clear structure.

2. Mode of Extension Module

var module = (function  (Module) {        function  () {        //  Another method !     };         return Module;    | | {});

The module can be extended by introducing the previous module.
