Why should I use asserts?

Question

I never got the idea of asserts -- why should you ever use them?

I mean, let\'s say I were a formula driver and all the asserts were things like security belt, helm

Answer 1

They enable you to test your assumptions. For example, let's say that you wanted to calculate speed. You would probably want to assert that your calculation is less than the speed of light.

Assertions are for development, to make sure you don't mess up.
