I know a lot about Typescript and its ecosystem. I’ve taught it to students, and worked on it at companies whose names you’d recognize. Claude Code is better than I am at some things that I know deeply, in some cases. It does stupid things on occasion (like use global mutable state), but it is still more useful than not. So, I guess it depends on how you define “better”, but I’ve learned things I didn’t know, and it allows me to do projects and experiments that I’d otherwise be too lazy to do.
