#Scala - Your First Programming Language - Part 20.2 - Case Classes in Depth

After having learnt about partial functions and pattern matching it is time to dive deeper and find out how to define pattern kinds of our own. For this we will have to refresh our knowledge about tuples. Learn about a new type called Option and dig quite deep down the rabbit whole to see all the magic behind case classes and discover extractors! This video got too long so it is split into 2 parts.

The Tuple/Product related API is here: https://www.scala-lang.org/api/2.12.4/scala/Equals.html https://www.scala-lang.org/api/2.12.4/scala/Product.html https://www.scala-lang.org/api/2.12.4/scala/Product3.html https://www.scala-lang.org/api/2.12.4/scala/Tuple3.html

The Tuple/Product related source code is here: https://github.com/scala/scala/blob/v2.12.4/src/library/scala/Equals.scala https://github.com/scala/scala/blob/v2.12.4/src/library/scala/Product.scala https://github.com/scala/scala/blob/v2.12.4/src/library/scala/Product3.scala https://github.com/scala/scala/blob/v2.12.4/src/library/scala/Tuple3.scala
