Nil is pretty simple - it represents nothing. But that doesn't mean that it's always easy to use, or that it's always the right choice when it appears to be the obvious choice.
We'll cover several anti-patterns in the use of nil. We'll discuss why they're problematic, and explore some better alternatives. The refactorings that we'll look at will help to reduce errors and optimize for understanding. Writing good code might take a little longer in the short run, but it pays off in the long run.
