Today I gave a lecture for GTUG Krakow about optimizations in JS.

My main topics were:
- Optimization in general
- DOM
- Reflow/repaint
- Garbage collector
- JIT
- Google Closure (Compiler/Tools/Library)
You can check my slides here. I collected plenty of links and wrote a few examples.
Feel free to comment and criticize. I’ll be happy to add anything that I’ve missed or to correct any mistakes. There are few good optimization resources and I had some doubts in few cases.



Hi!
Would it be possible to get a pdf form from this presentation? I tried both in FireFox and IE8 and did not got it to display properly
Thanks!
I’m afraid it’s impossible, there are some scripts embedded in presentation and you would miss a lot. It works at least in the latest Firefox and Chrome, try to update your browser. If it still doesn’t work, fill this form and send it to me http://supportdetails.com/
