+title: OpenTechSchool - Javascript for Beginners

+
+2 month ago I coached at OpenTechSchool's [HTML & CSS for Absolute Beginners][htmlfab] workshop.
+This weekend I once again helped at one of their workshops, this time [Javascript for Absolute Beginners][jsfab].
+
+What should I say? It was again a great experience. It were less learners this time,
+but the ones that attended where very motivated and eager to learn new things.
+The material ([Day 1][day1], [Day 2][day2]) was again provided by the OpenTechSchool movement and also translated into German.
+After just the first day, there were already great programs implemented, e.g. [a star system, with rotating planets and moons][planets].
+
+The second day was a little less packed, but again all attendees worked their way through the material,
+ asking interesting question and I did my best to answer them.
+But sometimes I couldn't and needed help from the other coaches or even a quick online search to give a correct answer.
+(Would you know how to describe the difference between `null` and `undefined` in Javascript in about 1-2 sentences to a first-time programer?)
+
+This time there was a small lottery. The [winner][bookwin] already blogged about his experience:
+[Cool JavaScript stuff I learned at the Open TechSchool workshop][dimsav].
+
+For this lottery I hacked a small and completely fair(!) winner-picker with the same tools/code also available to the learners.
+As requested the code is [available online in a gist][winner-picker].
+
+A big thanks again to the organizers of the [OpenTechSchool Dortmund Team][otsdo]!
+Spread the word, attend meetups and workshops and use the chance to coach!
