First was Robert Tomaszewski from Hypermedia Isobar with his presentation about different context of calling Js structures. He started with a little of JS history, then explained basics of using 'this' depending on placement of the objects and different approaches of using 'this' in DOM events.
Next was Marek Stepień - lead of Aviary.pl, team of programmers and translators localizing open source software for Polish users. He started with review of past JS objects, its restrictions and methods of its elimination. Then he presented new methods of creating objects in Js 1.8.5 like defineProperty() etc.
After the break there were a little contest - I won weekend stay in Karpacz for my implementation of adding function (Thanks!:) ). Just after that Tomasz Tunik talked about his Einie framework. He showed a lot of cool examples (like mouse tracking and interactions with canvas objects, or Pew! Pew! Towers, game created in 48h by Thomas and Szymon Pilkowski on HTML5gameJam in Paris. All of that examples are published on Einie's site so don't hesitate to check it.
Last presentation was made by me. I was talking about pseudorandom numbers and Steganography. I won't describe my talk, maybe someone else will, I think in couple of days I will publish it as a blog post or maybe little JS library.
I want to thanks the organizers one more time, and I hope we will meet on the next meet.js (or at least on Falsy Values:) ).
