C# like properties in JavaScript
var createProperty = function(getSet) {
var _value;
var autoImplement = {
get: function() { return _value; },
set: function(value) { _value = value; return _value; }
};
getSet = getSet || autoImplement;
var get = getSet.get || function() { throw new Error('No get method defined for this property.'); },
set = getSet.set || function() { throw new Error('No set method defined for this property.'); };
return function(value) {
if (value !== undefined)
return set(value);
return get();
};
};

Example usage:

var customPropertyValue;
var myClass = { };

// Auto-implemented proeprty
myClass.prop1 = createProperty();

// Custom getter and setter
myClass.prop2 = createProperty({
    get: function() { return customPropertyValue; },
    set: function(value) { customPropertyValue = value; }
});

// Read only property
myClass.prop3 = createProperty({ get: function() { return "read only"; } })

myClass.customProperty(123);
var value = myClass.customProperty(); // value = 123

Well, what I was looking for something like:
myClass.customProperty = 123; // sets value
var value = myClass.customProperty; // gets value

Note the difference from the last two lines of your example.
