Kotlin makes creating properties that are initialized on first access very simple. We will go through different options for creating them and how they can be really useful in our Kotlin code.

Entities in our codebases will commonly need identifiers or IDs to refer to them with. We will have a look at the different options for them and how to make them type-safe, allowing our code to be safer and less error-prone.

Modelling a type that can come in different forms, each with their own state, is a really handy language feature. We will look into how and when Kotlin sealed classes can be used and look at some use cases for them!
