Exactly. For a web dev oriented example, I would call coffeescript a transpiler, since it would transform

    # some comment
    myFun = -> 
       alert 'Hello CoffeeScript!'

into

     // some comment
     var myFun;

     myFun = function() {
         return alert('Hello CoffeeScript!');
     };

clearly intending the output code to be quite readable (even preserving comments).

Whereas Elm is a compiler since it transforms

  module Main exposing (main)

  import Html

  main =
  Html.text "Hello Elm!"

into

  (function(scope){
  'use strict';

  function F(arity, fun, wrapper) {
  wrapper.a = arity;
  wrapper.f = fun;
  return wrapper;
  }

  // about 4000 lines ommitted

  var $author$project$Main$main = $elm$html$Html$text('Hello Elm!');
  _Platform_export({'Main':{'init':_VirtualDom_init($author$project$Main$main)(0)(0)}});}(this));

Clearly not intended for (easy) human consumption.
