Using the negation operator, reverse the logic in the boolean statement.

Why I can't use unless instead if !(condition). What is more beautiful???

unless car_speed > speed_limit

vs

if !(car_speed > speed_limit)

Ugly coding detected.

Hiya there! Always use unless instead of if !(something). The latter one might create a bug if you've like nested if-elsif-else code blocks. Not only unless prevents 'em same bugs but it also makes it easier to read for human sets of eyes. Being said that, try avoiding if-else blocks ad replace 'em with ternary operators for good practices. I hope it helped!
