I can have a getter in a JavaScript object like this:
var member = { firstName:"XYZ", lastName:"zzz", get fullName(){ return (this.firstName + ' ' + this.lastName); } }
I can even add more properties on the fly, like this:
member.isGuest = true;
But, is there any way we can add getters to an existing object? Something like this:
member.isGuest = get isGuest(){ return this.firstName == 'Guest'; }

try defineProperty
Object.defineProperty(member, 'isGuest', { get: function() { return this.firstName=='Guest' } });
