What does zend; mean in Javascript [duplicate]

Question

While going through a new project source code, I immediately noticed something unfamiliar:

function(){
   var data = {},
       init = function(){},
       zend;

   return ..

}

So, what is zend; ?

It looks like it's just declaring a variable called zend. Note the commas at the end of the previous two lines: this is just a continuation of the var line. — Rup

@emix has it correct. Notice the , after init = funciton(){} it's just a continuation of variable declaration. — Tofu

It has no special meaning. In this context, it is just a variable name.

The code is equivalent to:

var data = {};
var init = function(){};
var zend;
