Just reporting that language-javascript seems to fail on macOS using the M1 architecture (Arm64), and I'm not sure how to make it pass: ``` bash-3.2$ locale LANG="en_AU.UTF-8" LC_COLLATE="en_AU.UTF-8" LC_CTYPE="en_AU.UTF-8" LC_MESSAGES="en_AU.UTF-8"...
I've been trying to minify Leaflet 1.5.1 with `hjsmin`'s `Text.Jasmine.minifym` function, but I get a Left value reading: ``` "HookToken {tokenSpan = TokenPn 87840 2829 23, tokenComment = [WhiteSpace (TokenPn...

The magic CommonJS constants `__filename` and `__dirname` are not available in ES modules. They’re supposed to be replaced by [`import.meta.url`](https://nodejs.org/dist/latest-v16.x/docs/api/esm.html#esm_import_meta_url), but `language-javascript` does not support parsing this meta property.
when `import` webpack function is used ```js exports.lazyLoadedImport = function() { var x = import( './Example.Lazy.LazyLoaded.purs' ) console.log(x) return x } ``` it throws error - ``` Unable to parse...
