I see Javascript made it mainstream for all sort of clients and servers, Electron desktop apps made it to mainstream.
So I remain skeptic to argument just because new features have been invented they are good or need to be implemented everywhere.
Been a fan of JS since before The Good Parts book. Used it server-side in Classic ASP, Netscape Server and a couple more obscure runtimes before Node.js.
Personally, I find Rust as more approachable and easier to wrap my head around opposed to Go. Though some of the syntax changes I don't like as much. Waiting on async/await to land in a couple months though.
No surprise there. Rust is most loved language in so many surveys. Most devs planning to learn in near future. Many say it will be polished and ready by next year. I personally feel it may be ready for general developers like linux desktop will be ready for general users next year.
I think it's already ready for a lot of use cases... though, I think baked in async/await will carry it across the line for many. It's good for low-level duties and even has some decent/good web server frameworks. The webassembly flow is better than a lot of tools as well. I think that there will be some work around nicer UI/UX tooling for graphical apps, but it's still very usable as it is.
I don't care about the features in the last 20 years if I'm able to do my job efficiently which Go as a language provides. Never wonder why those great academics languages with a ton of features are not adopted?
