An important feature in programming is to understand a piece of code at first sight. The more obvious it is, the better.
10-15 years ago, when Scala started to be used in real world applications, most people were excited about case classes. They provided a massive improvement over Java for a very common scenario: encoding an immutable record of data in a clear and concise way.
(Fun fact: Java only introduced a case-class feature in Java 16 released in 2021.)
Julien Truffaut has written this article, downloadable as a PDF below, for Signify Technology to share with you!
We wanted to provide you with useful code examples.
This is a continuation of our white paper (Scala 3: What to expect) which was more of a commentary.
Julien wanted to dive deeper into why he thinks Scala 3 is a much simpler language.
