Example of JavaScript method to define global objects

This article describes the method of defining global objects in JavaScript. Share it for your reference, as follows:

!function (factory) {
  factory(window['Hi'] = {
    __a: function () {
      ('Hi.__a');
    },
    __b: function () {
      ('Hi.__b');
    },
    __c: function () {
      ('Hi.__c');
    }
  });
}(function (Hi) {
  if (typeof Hi === undefined) {
    Hi = {};
  }
  (Hi, 'appName', {
    get: function () {
      return 'this is app name.';
    }
  })
});
();//this is app name.
Hi.__b();//Hi.__b

Pass the object (Hi) definition function as a parameter (factory) to the immediate execution function by executing the function immediately

!function (factory) { }();

In the immediate execution function, the object to be defined is passed as a parameter to the argument function of the immediate execution function.

The same object definition can be implemented as follows:

var myObj = myObj || {};
(function (myObj) {
  myObj.__a = function () {
    ('myObj.__a');
  };
   = 'this is ';
})(myObj);
();//this is 
myObj.__a();//myObj.__a

These definition methods are relatively independent and can be saved and used as functional modules of the Party Capital.

Plugin writing similar to Jquery.
