Chapter Overview
Explore how to handle impure functions in Elixir by using control-flow statements and error management techniques. Understand the benefits and drawbacks of various approaches including case, if, try, and with. Learn to avoid complex conditional chains and use pattern matching for clearer code. This lesson prepares you to write more maintainable functional programs by managing uncertain values effectively.

We’ve reached the end of the course. We’ve discussed the advantages and disadvantages of four strategies to handle uncertain values in functions. With this knowledge, we can promote changes in our codebase to achieve a low maintenance cost.
Let’s review what we’ve learned in this chapter:
- Impure functions can
