That's totally fair. The OP seems to be intended for your main page logic: > TypeScript is still second-class citizen with regards to browser adoption, there is a proposal to fix that, but until then we have to use tooling, bundlers, build steps that are an impediment for when you want to quickly create a short demo or PoC. (Of course, just for "a short demo or PoC," but will anyone be motivated to rip it out before that's no longer feasible?) So I assumed you were talking about something similar. But using this approach to compile user code makes a lot of sense.
