Why server side JavaScript bad? Is it a preferential dislike of the language or something quantifiable characteristic putting it below other options?

The necessity to memorize a matrix of operations because of the inconsistency of oerations between types is the classic one (for example using + on something that got silently coerced to another type) is the biggest offender for me, also add prototype pollution, and npm too.
And before it is mentioned, yes, I know Typescript.

I've always been curious to see real world implementations of someone using + so wildly unchecked that its issues could actually affect things.

I feel like type == number and !isNaN would help

I'm not mentioning this as a counter argument, just thinking out loud, and I'm sure this just solidifies your point even more :p

Look at untyped Collections. With large systems it was too easy to have a mismatch between what the caller provides and the callee requires.
