JS VMs are generally better engineered than Ruby VMs due to more investment, including better JSON handling code yeah. But that’s nothing to do with JSON being (almost) a subset of JavaScript. Unless you can think of a concrete reason why?

Is that still true? Shopify is investing a whole lot (u don't need me to tell u of course). Yes I know Google/Firefox etc had teams working on JS but did they invest that much more than Shopify?


Yes, both in terms of money and dev-hours, I wouldn’t be surprised if Google put 2 orders of magnitude more resources into V8.

Nonetheless, Shopify’s investment into truffleruby may well be worth it, as it builds on top of the many many work-hours that went into the JVM.


Nono, I agree with you, I think I was wrong above, as I wrote above it was probably just a psychological bug. But I still think there's much room of improvement with the tools we already have.
