I would like to join to the question by extending it (somewhat shamelessly). Do coding assisants already exist that only comment on your code in another window instead of writing it? Something like: fs.promises.readFile(in_fi| You probably want 'utf-8' as a second parameter here, cause from the context I infer it’s a text file. Also, I see there’s a stream set up above. You can simply pipe a file stream to it, if that’s why you’re reading it: <link> Is there something like this?
