[Javascript] function object/custom object prototype confusion

[Hakan M (Backbase)]

Try:
Person.prototype.toString = function() {
	return this.first + " " + this.last;
}

I try to create all methods/properties of my prototypes in one go. In 
that fashion, you could fix it like this:

window.Person.prototype = {
	first: '',
	last: '',
	toString: function() {
		this.first + ' ' + this.last;
	}
}

Regards,
H
