> I sometimes wonder if JS programmers know that with C#/VS you can just change the name of a class

How exactly does this knowledge help? I know this is possible and I do miss it. But it's extremely diffcult to support it in JS because of how the languages works. VSCode tries, but it's still limited. So should we all switch to writing C#? You can't avoid writing JS if you want to create a web app. There are tools to avoid it, but one has to know what's under the hood or they'll have a bad time.

TypeScript is doing great progress on this part, and it supports easy refactors, but it's still lacking in some parts, for example the type inference is still poor when it comes to complex cases and the type declarations depend on will of maintainers.
