Assertion definition language

Okay kiddo, have you ever played a game where you had to check if something was true or false? That's a bit like how computers work too. They need to check if things are true or false so they can make decisions. But instead of playing a game, they use something called an "assertion" to check if things are true or false.

Now, an assertion definition language is just a fancy way to write down those instructions for the computer to check. It's like writing down the rules of the game so everyone knows how to play.

For example, let's say we have a computer program that adds two numbers together. We can write an assertion in an assertion definition language that says "when I add 2 and 2, the result should be 4". The computer will check if that's true or false and if it's true, it knows it did its job right.

So in short, an assertion definition language is a way to write down instructions for computers to check if things are true or false. It helps make sure the computer program works right and does what it's supposed to do.
