> Type annotations for dynamically-typed languages is just a bad idea.

Yet, as with the parent comment, you haven't divulged your reasoning behind this statement. If you're going to make such a broad statement, at least place your rationale beside it.

> JavaScript's only reason for existence is web browsers.

JavaScript has seen broad adoption throughout the industry, for servers (Node.js, Deno, Bun), IoT (DeviceScript), browsers (duh) and mobile apps (NativeScript, React Native, etc.). It has its weak points, but downright dismissing it (again, without any rationale) is unfair and disingenuous IMO.

It breaks the whole point of typing being dynamic to begin with.

You don't build static typing on top of dynamic typing; it's silly. You do it the other way around.

If you're going to be outside of the browser, just use Python, which is not only somewhat similar but also the world's most popular programming language.
