In this video we'll explore various ways of handling errors in Scala, from the simplest and most straightforward, to the more complex and more powerful. We'll look at the try/catch structure that we can also find in Java, then we'll distance ourselves with Try, Either, and finally Validated from the Scala Cats library, discussing the pros and cons for each.
