Should implicit classes always extend AnyVal in Scala?

February 10, 2023February 13, 2023Studio-Scalaimplicit classes, scala

Reading Time: 3 minutes What are implicit classes? Implicit classes are a feature that allow you to extend the functionality of existing types by adding new methods. They are defined using the implicit keyword and have a single constructor parameter. We can use these class as if they belong to the original type without having to perform explicit type conversion. Implicit classes are particularly useful for adding utility methods Continue Reading
