missing name after . operator ?

[Luke Murphy]

Hi,
This is from the book 'Javascript the good parts'.

var add = function (a, b) {
	return (a + b);
};

var myObject = {
		/** myObject has two properties, value and increment **/
		value: 0, 
		increment: function (inc) {
			this.value += typeof inc == 'number' ? inc: 1;
		} 
};


myObject.increment();
print(myObject.value);

myObject.increment(2);
print(myObject.value);

myObject.toString = function() {
	return "0";
};

myObject.double = function () {
    var that = this;    // Workaround.

    var helper = function () {
        that.value = add(that.value, that.value)
    };

    helper();    // Invoke helper as a function.
};

myObject.double();
print(myObject.value);

I have replaced the document.writeln() with print() so that I can run it in eclipse with rhino.

When I try to run it, I get:

js: line 24: missing name after . operator
js: myObject.double = function () {
js: ...............^
js: line 32: syntax error
js: };
js: ^
js: line 34: missing name after . operator
js: myObject.double();
js: ...............^


Any ideas?

double is a JavaScript reserved word and cannot be used as a property name using the dot notation.
