Ironhack Barcelona is a bootcamp teaching non programmers Ruby and javascript. In their meetup they invited me to introduce scala. Several non-ironhackers (senior and java background) signed up so this is a talk that's partly intro to scala for a junior from Ruby and some more generic advanced concepts.
