C# and FP – episode 2 – OOP today, (im)mutability.


An object’s state, describes its current condition. If object was a human, this could be their emotional state (e.g happy, sad, angry). To think a bit further, the height value in an object’s field is not a state, but the height’s value help us to define it’s height category (e.g tall, short, average), that is actually the state. And it is the state, based on the context we, as society, have set on defining when someone is considered tall or not.
