how can you compile it if javascript is a valid subset of typescript? confused.

  Either it is only accepting a subset of TypeScript, or it is still interpreting the parts that don't have enough types. Given other comments here it sounds like the later.

    Both, basically. Default is the subset, but you can enable an interpreter
  • lpribis 2mo ago
    No idea about this project, but it is very possible to compile a dynamically typed language, without large VM/runtime. See Common Lisp, Julia
    • panzi 2mo ago
      Yes, and JavaScript itself is JITed. I used interpreted here as a shorthand for interpreted and/or JIT compiled at runtime.

  What it can actually compile is a subset of well-behaved typescript. For anything else it bails out and asks you to ship a JS engine (albeit, not NodeJS) again.
