How was it to switch from beautiful Perl to horrible JavaScript [rus]

Talk presentation

I use JavaScript from 2006. That time I did single-page applications for IE6 in JS (it was ES3) and backend in Perl. JS was a pain. Does it better now? During my talk, I would like to show the fundamental difference between modern JS and Perl. How the same problems can be solved in different ways. Hope to give you a broader view on what programming languages can provide. Be prepared for interaction and to help me with simple tasks/problems in JavaScript :)
