I think the argument was/is not "its a problem we cannot have javascript" but "if we can have javascript everywhere, we only need to hire javascript devs and only need to care about javascript tooling", which is a fair point.
That does ignore the fact that an experienced frontend JS dev is not necessarily also a good productive backend JS dev, but at least they know the language basics, can use the same IDE, etc.
If thats worth it is something that depends on what you try to achive, I guess. I personally would not pick JS (nor TS) for the backend.
