Extension Methods, Part 2

In this free Scala training video I show more about how to create extension methods in Scala 3. I show how to create an isBetween extension method and put it in a Scala object. Then I show some details about how to write a Scala String interpolator, and discuss the s, f, and raw interpolators, and then mention how programmers create other interpolators like sql and json. Finally, I show some details about creating my Q interpolator.
