Material on typeclasses in Scala #21

Closed ghost closed 8 years ago

ghost commented 8 years ago

I'm looking for further reading material on Scala's type classes. I've read Oderskys chapters on the topic, and the following video https://www.youtube.com/watch?v=sVMES4RZF-8&feature=youtu.be

I am however not entirely sure what all of the applications of this feature is. The scala-lang.org website doesn't explicitly have any sections on typeclasses. What is another name for typeclasses, so I can Google for further information?

It's not that hard to grasp once you see it a couple of times in action. Then, you'll realize that what the video guy says is quite straight forward and makes a lot of sense. It's just as he says, you can inject functionality for an object into your code (without touching the object itself). As he says, it's especially useful with implicit resolution.

If you want the theory, I guess you should go towards Haskell reading, although it's probably tough if you don't have exposure to that kind of language before. Sorry, don't know any other resources. There are probably no clear synonyms.
