This article is part of the Scala knowledge bits Series.
Periodically, I will publish new exercises so you can slowly build up knowledge about Scala.
It is designed to be done in a very short amount of time and learn a little bit each day, just to create a routine.
This episode will teach you about Scala
Hope you are going to enjoy it! It is designed for anyone to learn Scala from scratch and slowly learn, one Bit at a time.
After this Bit, I would love to hear your feedback in the comments down below.
Feel free to join the Discord server as well if you would like some help and support from the rest of our community.
What are we learning today?
Today we are going to learn about Scala
I want to introduce you slowly to more complex problems. This one is still fun, as you know, the main topic is
but you are going to get an intuition for a little more.
Enjoy the ride.
Time to try on the exercise on your own and scroll down for more information when you are done or if you are stuck.
Here is an exercise to complete today.
If I did my job well, you should be able to guess by yourself the solution based on what you previously learned and based on the clues.
But if you get stuck, scroll down to get more information.
The goal of the exercise is to replace the
by a piece of code so that the exercise compiles and that’s how you win! Good luck!
You can fill the exercise right in here:
Or, if it does not load, go on to Scastie (ldCLOORGSEGwvfDOlUKDWA).
More information about Scala
In this exercise you will learn (or have learned, if you have already solved the puzzle) about Scala
Did you get
? It is
. Try to replace the
in the code above by
Ok, now that the topic of today’s episode is done. What is the wizardry with all the
?! This is called pattern matching. I am sure that, right now, you have a good intuition about it, but we are going to dive more into it, soon.
Feel free to go back to the exercise, modify the code to try out new things and get a better intuition for Scala
I hope you have learned something new or had fun during this Scala Knowledge Bit.
