    Here is one of mainly used dependency: Cats Effect
    Cats is a kind of "ecosystem" for functional programming in Scala
    And Cats Effect is a library of code for dealing with "side-effectfull" computations
    
    Cats is implicit dependency of Cats Effect. You can check dependency of library in few places:
     * on mvnrepository (or other repository): https://mvnrepository.com/artifact/org.typelevel/cats-effect_2.12/1.2.0
     * on source code: https://github.com/typelevel/cats-effect/blob/master/build.sbt#L258
                       https://github.com/typelevel/cats-effect/commit/8b1ba209fde878296eade713ca651aca3b626ea1

    Good practice is, when you use implicit dependency in your code, making this dependency explicit.
    So here is Cats library. Alternative to Cats is Scalaz. Check out the comparison of these and join discussions:
