Feeling absolutely the same way these days (with 10+ years of experience with JS). My current breath of fresh air is Go and Swift (despite the fact XCode is the worst IDE I have ever worked with before). Curious what’s bringing back sanity for you?
Rinse and repeat.
The only thing that's really missing to me is bundling, which feels like a bit too big of a project to tackle on my own. But my current projects aren't big enough to need that, I'll pass that hurdle when it comes. And I may have to run webpack as a separate build process through node, but luckily I can do that in a CI container, and keep my dev machine clean.
