Javascript started as a slow, interpreted language, but in more than two decades things have changed completely and now we have even game engines running in the browser.
What is its maximum theoretical performance, and how can you write code that exploits its full potential?

As always, an amazing talk

Amazingly interesting!

just interesting :)

It's impressive what you can do with JavaScript nowadays and Massimiliano did a great job to show it. Great insights about V8's internals and excellent optimization general-purpose tips.

I did not expect this level of detailed information. I learned a lot and now eager to try emscripten :)

simply awesome!

Mind = blown

Great insights into how V8 works, I learned a lot.

Great! For me the most interesting talk. Thanks also for the extra-time explanations ;)

Very nicely structured talk, and to the point, IMO too many assembler slides which are hard to process

I was not expecting this level of details when it comes to Javascript optimization but it was really great. It is obvious that the speaker has so much knowledge on this subject and I could have sat so much more than actually 25 or 50 minutes. This speaker is surely one of the best surprises I had at this conference.

the truth is that these tricks are known from ages, ad example when the home computers where having an interpreted basic and you where trying to make some cool that required performance.
Good thing to show these concepts nowadays

Great talk.

One of the best talk of the whole conference: inspiring and with a good rhythm.
Well done Massimiliano!
