private variables in javascript

Found a nice post about private variables and “methods” in javascript. Consider this example:

function Pizza() {
  var price = 0;
  this.setPrice = function(p) {
    price = p;
  };
  this.getPrice = function() {
    return price;
  };
}
```Every variable and function inside the main function is private unless it is appended to "this".
