This whole chapter is dedicated to conditions. We've met conditions previously but we haven't dedicated enough time to really understand them. In this chapter we dive deep into the world of conditions: if, if else, else if, switchs, cases and more. Conditions are crossroads in our code. In many ways conditions are just like intersections, or more accurately delights in an intersection. Conditions help us steer directions in different ways helping us to create unique experiences for users that change as conditions change.
