Strongly-typed identifier

A strongly-typed identifier is like a name tag that you wear on your shirt. Just like how your name tag tells everyone your name, a strongly-typed identifier tells the computer what kind of thing it is looking at.

For example, if you have a box of apples and a box of oranges, you want to be able to tell the computer which box you are working with. A strongly-typed identifier helps you do that. You might give the box of apples the identifier "appleBox" and the box of oranges the identifier "orangeBox".

This way, when you tell the computer to do something with the appleBox, it knows that it should only do things that work with apples, like counting them or sorting them. And when you tell the computer to do something with the orangeBox, it knows that it should only do things that work with oranges.

Having a strongly-typed identifier is like having a label on the box, so everyone knows what's inside and how to handle it.
