TypeScript is to JavaScript, as XHTML is to HTML.
XHTML was abandoned bc it was brittle.
It's still incredibly pleasing to run through old projects converting TS into JS + JSDoc.
I made the decision to cut out TS (excluding `.d.ts` files, they get a pass) from all my personal projects years ago and I'm still very much convinced that's the right move. TS as an authoring format ain't it.
