JavaScript private methods

Question

To make a JavaScript class with a public method I\'d do something like:

function Restaurant() {}

Restaurant.prototype.buy_food = function(){
   // something         


        

Answer 1

Since everybody was posting here his own code, I'm gonna do that too...

I like Crockford because he introduced real object oriented patterns in Javascript. But he also came up with a new misunderstanding, the "that" one.

So why is he using "that = this"? It has nothing to do with private functions at all. It has to do with inner functions!

Because according to Crockford this is buggy code:

Function Foo( ) {
    this.bar = 0; 
    var foobar=function( ) {
        alert(this.bar);
    }
} 

So he suggested doing this:

Function Foo( ) {
    this.bar = 0;
    that = this; 
    var foobar=function( ) {
        alert(that.bar);
    }
}

So as I said, I'm quite sure that Crockford was wrong his explanation about that and this (but his code is certainly correct). Or was he just fooling the Javascript world, to know who is copying his code? I dunno...I'm no browser geek ;D

EDIT

Ah, that's what is all about: What does 'var that = this;' mean in JavaScript?

So Crockie was really wrong with his explanation....but right with his code, so he's still a great guy. :))
