Man I need to do a sudo apt upgrade on my brain: I read the title and thought he was talking about ELM the email client, and was like: yeah, we all stopped using that in the early 90's when zmail showed up.
I agree that HN is quite serious, that's why I rarely comment. I'm actually a fun person lol
This "Elm" is some sort of JS precompiler, claiming a better program's name? Join the post-ES6 scrapheap with CoffeeScript, TypeScript, and every other joke precompiler. Write JavaScript in JavaScript, and if it's not sufficient, file bugs on ES6/7.
