Haha, good point. I don't have time to go into much depth right now, but basically the ascendent languages don't seem to offer many compelling technical advantages. For example, I've yet to hear a compelling reason why JS makes a better serverside language than Ruby for most use cases. To be fair, Node and some of the JS libraries for a long time offered advantages over the Ruby ecosystem for things like websockets (EventMachine used to swallow stack traces in a really annoying way). But that has more to do with the ecosystem than the languages themselves. I think part of the problem had to do with how dominant Rails was/is in Ruby. I wish a framework that better catered to emerging app design trends had gotten traction in Rubyland in, say, 2012. As for specific complaints about JS, well, it's a perfectly fine language, but I don't think it's an improvement in any way over Ruby. It has a number of quirks and compromises - prototype inheritance, basically no support for modules, clumsy typing, to name a few - which people have been patching over and working around in lots of different ways over the years. You end up with a forest of different solutions to things that wouldn't have been a problem in other languages. Now some fairly dramatic changes are being introduced, which is probably good, but it means the ecosystem is even more complicated. Working with the JS ecosystem feels like working with a poorly maintained legacy codebase - there are lots of places where people have come up with workarounds to things that shouldn't have been a problem in the first place; it makes you tired just thinking about all the mental energy spent solving all the little unnecessary problems.
