javascript - Can I create a function that's a property of a function in an object? -

i access function within object this

    function myobject()     {         this.create = function(array)         {              var myarray = array;              this.arraylength = function(){return myarray.length;}               // else here...         }     }     var foo = new myobject();     foo.create(value);     console.log(foo.create.arraylength();); 

i undefined response .create.length(), possible way?

when call .create() method foo.create(), within .create() this foo. line:

this.arraylength = function(){return myarray.length;} 

creates method arraylength() on foo. use:

console.log(foo.arraylength()); 

if reason want arraylength() method of create this:

this.create.arraylength = function(){return myarray.length;} 

and use original:

console.log(foo.create.arraylength()); 

(minus semicolon before closing bracket).

but while latter version "works" seems kind of strange way go.
