I am sorry. I really don't see your point. Typescript is in a completely different league of languages than rust/c/c++ with vastly different use cases.

Also, the world still mostly speaks C99 when iterative improvements are constantly being made up to C23.

The point is that Typescript was able to replace JavaScript by adding to it. Converting a codebase from js to ts was simple. Going from C++ to Rust is not.

I think C23 is going in the right direction, but it needs to go further.

Typescript isn’t a separate language though, nor does it replace Javascript, you’re comparing apples and oranges.
