All your points are good, thanks, especially about the unused functions.

> many people want to use typescript or jsx when writing their code

However, if this is true, why don't we just add these languages to browsers (<script type="text/jsx">, <script type="text/typescript">) with some kind of client-side processor for old browsers that turns them into "text/javascript" in-line in the DOM if the browser doesn't support it?

It's kind of weird that JavaScript is becoming a common "bytecode" among other better-structured languages, one would think the bytecode language that becomes the compilation target should be one that is better designed of its own.

If we're compiling JS, JSX, and TS all to some sort of assembly, or even a statically and strongly typed language like C++, I would feel a bit better.
