      We’re seeing numbers on mobile that suggest that JavaScript can be faster than native end to end due to I/O costs for loading the code from disk. On web this matter even more because the network cost. JS haters need to embrace I/O over CPU perf if they want to win.

      Are you saying that the JS code tends to be smaller or that it isn't loaded from disk?

      JS code tends to be smaller because of the encoding (and the ecosystem). So it’s faster to load from disk (or network). It doesn’t mean it’s ideal and other languages can beat it in theory but they haven’t done the work yet. The point isn’t that JS is inherently better.

      Ok, so basically it's that the JS ecosystem is -Oz and everyone else is -O3? iow the web is the first time in a while that people tried to build significant production software in small size-to-boot in a long time and everyone else is built on "size is not important"?

          Exactly. I think it goes beyond that. There is an elitist associated with those communities that consider the JS approach is purely subpar. Web assembly will hopefully surface the bitter truth of this tradeoff.

          Yeah. The whole "drive-by web" as a synonym for crap really misunderstood what makes the web tick. The web has an extreme perspective on performance where a "slow boot" is counted in a small number of seconds, and we're paring it down to sub-second.

          And somehow this is all done while parsing, compiling and executing a dynamic language. It's not like other ecosystems can't do it, it's just that they haven't tried anything even remotely similar.

          I think it has not seen as important. High-end games has gotten a free pass where as small peripheral games that need this are seen as low-end even though it’s big business.

          High end games have literally minutes-long loading screens. They've been given a pass as responsive experiences we should strive to reproduce despite that. Pretty sad.

      Loading seems to be taking a while.
