The hardest part by far has been just setting up a TypeScript project with NodeJS and Vitest

proper hiking probably not in the cards for me anymore but it sounds like i’ll be in the bay area for work a couple times a year now so looking forward to seeing you!!

trying to figure out which variety of “mid-30s guy” i want to become and they all suck lol

I was thinking of dropping unused methods I think, which IIRC is enabled via method devirtualization (github.com/google/closu...)

Just to sanity check I tried repro-ing this in Closure Compiler and it seems like it also retains unused properties on object literals: closure-compiler.appspot.com/home#code%3D...

(I've also verified the same behavior exists with Tsickle)

Actually it seems like this is an issue even when using a single file: rollupjs.org/repl/?versio...

This is very exciting! I've been hoping a compiler other than Closure Compiler would support this kind of feature for ~years.

Not sure if it's a bug, but it doesn't seem like this works across file/module boundaries: rollupjs.org/repl/?versio...
