When refactoring, our intent is to improve the state of the code without changing any of it’s behavior. As I make changes, I like to have immediate feedback telling me that my changes did not affect the behavior of the code. The best way I know how to do that is to write tests.

Can You negate conditionals in an IF statement?

When dealing with nested if statements like this, you can negate your conditionals in order to flatten out your code.

How do you write multiple conditions in a case statement in SQL?

How to add an additional column to an if function?
