Let's continue the pattern matching exploration.
How would you match several conditions at once ? We are going to learn this today.
Once you know the syntax, it is pretty straight forward, you have to use the symbol |. Like the boolean operator OR: ||.
The syntax is:
case valueName @ ( enum1 | enum2 | enum3 ) => ...
You can also do the same thing without the @:
case ( enum1 | enum2 | enum3 ) => ...
And you can do the same thing with case class:
case valueName @ ( CaseClass(_, exactMatch) | CaseClass(match2, _) ) => ...
Next time, we are going to dive more into the case class use case.
