Nice description of what's in the React library. I didn't know there was already so much work done. More real-world examples would have been nice, especially in the last part (websockets etc.)
Very good talk, started with the basics, and covered almost everything there is to know about regexes. Some more advanced examples would be nice however.
Very passionate and pleasant speaker.
Great explanations throughout the presentation, supported by cool analogies and sketches, making sense all the way to the end.
I became aware of the existence of several libraries => something new to play with => happy to have attended.
As a suggestion maybe another demo could have been prepared even if not interactive but in case the interactive one failed.
Nice one.
Maybe the talk was lacking some structure, I don't know. I also saw this one https://www.youtube.com/watch?v=i5Y5QPcYWHw&list=FL9LMd20FSxH6JIV-vNex71A and found it much more inviting. Like Mattias said, maybe add more code examples about how to actually build something with it (by using / extending it).
The slide titles were sometimes unreadable. Good speaker that brought us a lot of good protips.
Interesting topic and well delivered. Good job!
Lunch was ok. But it would be nice if there was something changed to the way people get there lunch. 350 people walking to 2 tables will give you a large queue. Same for coffee. We all know developers drink lots of coffee. But it all these cups have to be served by 2 persons the have to work hard.
