Sorry but this reply is just kind of vacuous given the link I posted. Eric Lippert gives a pretty detailed, neutral, blow by blow summary of the issues working with js at scale. And he quite specifically says that dynamic typing is not intrinsically the problem, just that dynamic typing tends to be correlated with other things that are a problem. He specifically mentions things like error handling. Did you even read the link?

I think your attitude is more that nothing is really bad with js relative to other languages, more so than actually trying to understand why it draws a lot of criticism, which is what you claimed and what I tried to link to.
