The simple solution is to write everything (for the browser) in TypeScript instead and treat JavaScript only as the compilation target noone actually talks about. And compiling to JavaScript might also become a thing of the past with Webassembly. So, I think we shouldn't care about JavaScript as a name.
Not everyone doing things on the web is a pro developer using typescript. There are millions of use cases for plain-old javascript in the browser to get work done, probably many more cases of that than there are pro developers using typescript.
