      you're saying they don't exist. He's pointing out that the JS ecosystem has an established use of the term as a subset of the term "compiler", which you're kinda erasing. (There's a difference b/w "transpilers don't exist" and "all transpilers are compilers too")

      Having names for arbitrary distinctions isn't necessarily a good thing. Coining the term "Janpiler" for compilers that were first used in January would make discussion more confusing, not less.

      On the other hand, we have terms like "C compiler", "linker", "assembler", and many others, which are kinds of compilers. You can't just assert that a distinction is arbitrary, you need to say why you think this distinction is arbitrary and pointless.

      Right, I agree with that. It's just that "targets JS" includes Babel, Clojurescript, some LLVM backends, and some GHC backends, but not other LLVM backends or GHC backends or Clojure.

      "Targets a version of JavaScript that is not the most modern but exists on the bulk of my target computers" is roughly what the term is trying to convey. It doesn't have to be perfect. It's English. But it's not very similar to Janpiler.

      Sure, and "can target an ARM processor that's not really old" is a similarly useful thing to know but we don't call GCC and armpiler.

      It doesn't make sense to call GCC an armpiler because it has other purposes. In any event, I think it's silly to single out "transpiler" for being a pointless distinction, and I think it happens because of "those JS kids" feelings.

      As someone who has been on the "down with the T word" for a decade now, it has never been about that, but in fact the opposite. Also, if that's true for GCC, then what's different about emcc, which is mostly just clang these days?

      I’m hesitant to weigh in but for me “transpiler” has always meant “a compiler that transforms a high-level language to high-level language”, inheriting all the fuzziness in the term “high-level language”

      Replying to @pcwalton @samth and

      By this definition no C/C++ compiler is a transpiler, nor is any compiler that targets assembly or an IR like JVM or .NET bytecode. But Java-to-JS would be a transpiler because source and target are both high-level.
