How can you even form an opinion on this if, as you stated in that thread, you literally have no idea what typescript is and are just a beginner in js? You got down voted for saying typescript is unnecessary without even knowing what it is or what the thing you're working with's limitations are, which is a pretty objectively braindead stance to take. You're a beginner js developer, you have no idea what you're talking about when it comes to preferences of ts vs js, just that all of the beginner level stuff you have tried to do works in js so therefore typescript or frameworks must be unnecessary
