    Awesome and thank you!

    These pattern matching exercises have clear my mind and now I feel more confident. In the beginning I thought I wouldn’t complete the exercises without looking at the solution but gave them a try, read my notes, and tests passed!

    The second one was a tricky one, though, but was a nice thing to learn.

    Is it a better practice to create multiple function clauses or to create one clause with a case statement?

      It’s a good question and this may sound like I’m dodging the question, but I’d say it really depends. 🙂

      I prefer a case statement when the code is pretty simple. Like just a simple transformation. When the body of code in a case clause starts to get more involved or complex, I think about doing it differently. Separate function clauses can be easier to test as well.

    Sometimes reading some code I notice I needed to practice and put in my mind exactly these things.
    And here was a good sample to blow my mind.
    I like the exercise with tests, It was very helpful.
    In some books you don’t see this important things you need to understand and it’s very simple now for me.
    Thank’s!
