How to use protected variable in javascript? [duplicate]

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

@dandavis why do you think so? In js we can make sense of use classes/subclasses/superclasses. — Navin Rauniyar

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