It's barely transpiled. There are a couple of features that involve actual code generation - enums and namespaces (which are almost never used), but the vast majority of it is just stripping the type annotations so the performance will be 100% identical.

It's like having "Python" and "Python with type hints" as separate languages and claiming there is a big speed difference between them.

I was originally going to comment that differences in performance between JS and TS appear to be most significant in one challenge

ascii table about that, not screen reader friendly

however, trying to look to see the typescript code, wanting to translate that to type hinted python code, I've been unable to find typescript on CLBG, so I'm confused on how they got that data,

They used to have Typescript. Looks like they removed it at some point.
