Javascript automatic getter/setters (John Resig Book)

Question

I\'m reading \"Pro Javascript Techniques\" from John Resig, and I\'m confused with an example. This is the code:

// Create a new user object that accepts an          


        

Answer 1

EDIT: now, adapting Jason's answer, it works:

We need to make a closure for the values. Here's one way:

function bindAccessors(o, property, value) {
  var _value = value;
  o["get" + property] = function() {
    return _value;
  };
  o["set" + property] = function(v) {
    _value = v;
  };
}

Then the User constructor looks like this:

function User( properties ) {
  for (var i in properties ) {
    bindAccessors(this, i, properties[i]);
  }
}
