How to use init method in javascript

In JavaScript, the usage of the init method is "init:function (parameter) {js statement to be executed}". The init method is an initialization method, which initializes the entire page; if the init function is not called, the code in it will not be executed.

The operating environment of this tutorial: windows7 system, javascript version 1.8.5, Dell G3 computer.

Recently when I was studying the MUI framework, I saw this code:

init: function(options) {
      var that = this;
      ……
  }

init, there is another layer outside this:

var _App = 
    init: function(options) {
        ……
        },
    ……
};
        ……

It is somewhat clear, it is just like in java An init method is defined in the object. The init method here is also an initialization method. Here, the entire page is initialized. Just call something like java:_App.init().

About the details: This is a json writing method. Use var o = {x: func, y for all functions, all variables, etc. : "", z: obj} this kind of architecture.

This class-like understanding means that var *** is regarded as creating an object, x: func defines a method, y: "" defines an attribute, and z: obj defines another object. Overall, it is similar to json writing {x: ***, y: ***}
