It's incredible how I don't need tooling at all, except for a basic IDE integrated language server. No package manager, no transpiler, no linter/formatter, no extensive configuration files. Need to add a dependency? Just copy paste the code you need from a github repo. It's still readable and editable if you need since it's the source code, not some transpiled/minified/optimized mess.
Ever had ESM/CommonJS dependencies conflicting with your tsconfig.json, right when you need to deploy an urgent hotfix? Forget about that madness. It is such a great and simple DX compared to JS.
Edit: Before I'm dismissed, I'll add that my Odin project is becoming as complex as any other JS website I've worked on and it can run in a browser thanks to wasm compilation. So I'm not even comparing apples and oranges.
