Hey, can anyone explain to me what the difference is between a getter/setter and a delegate?

nyxcode: You might have a Person with a money property which has a getter and setter function. The setter indirectly sets the money using a Wallet instance. (person.setMoney(99) calls person.wallet.setMoney(99) for example.) Wallet in this case is the delegate -- Person delegates money storage to Wallet. Kotlin has a special notion of a delegate: You can alternatively give Wallet special operator functions getValue() and setValue() which can make the code a little prettier in some cases: var money: Double by Wallet()

So.. It's just syntactic sugar for a getter/setter?

That's a reasonable first order approximation
