Are there well known patterns to use for creating method chaining in javascript?

Question

What is the best way to implement method chaining in javascript?

function CONSTRUCT(){
    this.func1=function(insert_ob){insert_ob.appendTo=this;/*other code*/};
    this.func2=function(...){};
    this.func3=function(...){};

}

function My_Object_Creator(){this.appendTo=null;}

object1=new CONSTRUCT();
my_object=new my_Object_Creator();
object1.func1(my_object).func2().func3();

I know I can adjust those functions to in the constructor to achieve it but I want to know if there are some well-known methods or patterns one should follow while creating method chaining possibility in javascript?

The most basic way to method chain is to return this (or a reference to the object).

That's not the only way to method chain at all – Esailija Jun 11 '14 at 14:39

@TJHeuvel try `"asd".split("").reverse().join()` all of those are not only different objects but objects of different types – Esailija Jun 11 '14 at 14:41

@Esailija that isn't what the OP is asking. – Daniel A. White Jun 11 '14 at 14:41
Also, you could return other (new?) instances or private variables, not only the `this` object that a method was called on. – Bergi Jun 11 '14 at 14:42
@DanielA.White: I could not find the good reference on how to accomplish the method chaining in my code so I was expecting somebody could point me in a right direction on how it is done. – Jack_of_All_Trades Jun 11 '14 at 14:43

@DanielA.White He is asking how to do [method chaining](http://en.wikipedia.org/wiki/Method_chaining) isn't he? how is that unclear – Esailija Jun 11 '14 at 14:43
@Esailija and thats the basic case is. – Daniel A. White Jun 11 '14 at 14:43
@Esailija: You are absolutely right. I want to know how to do method chaining in a proper way. crude way using some brute force, I think I can manage but proper way that can enhance code-reusability, I don't know. – Jack_of_All_Trades Jun 11 '14 at 14:45
