How to use protected variable in javascript?

Question

In php we can define variables mainly in three ways:

In javascript we can define variables like this:

function myfunc(){
    var x = 'private'; // private variable
    this.x = 'public'; // public variable
}

Now, I want to know how can I maintain protected variable in javascript?

Is this an answer?

function myfunc(){
    var x = { //private variable
        protectedVariable = 'protected'; //protected variable?
    }
}

private and protected are about the same in js, since there are no classes/subclasses/superclasses — dandavis, Jul 03 '14 at 03:47
@dandavis why do you think so? In js we can make sense of use classes/subclasses/superclasses. — Navin Rauniyar, Jul 03 '14 at 03:50
this is as close as i could come, but yuck: http://jsfiddle.net/YPSLT/ — dandavis, Jul 03 '14 at 04:16
@NavinRauniyar: i can't or i would have (duped). it's rough anyway, but you could make the nitty gritty repetitive parts into a callable re-usable routine to give you a sugary way to declare that capability inside the constructor, if you really wanted to use the pattern. personally, i would stick with what's built-in to JS... — dandavis, Jul 03 '14 at 04:47

You can define private scope in JavaScript using closures, but the language doesn't support granular scope identifiers like PHP does.
