Sure if you prefer static typing then JS is not for you.

I did not say anything about static typing. Most dynamic languages are not forced by their specs to coerce disparate types into utter garbage. I invite you to type the examples in the Wat talk into a REPL for any other dynamic language and see how many of them produce exceptions.

Continuations seem to be rare among other languages you could choose. Personally I have only seem them in LISP, what else is out there?

Before answering, I will point out that coroutines are equivalent to one-shot continuations, and coroutines that can be copied are equivalent to multi-shot continuations. Then, I am familiar with continuation implementations in the following languages: Python [1][2], Scala with any JVM runtime[3], Any JVM language with a particular runtime[4], C[5], Lua[6], Julia[7], and C++[8]. Of these, the ones for the JVM, C/C++, and Lua[9] are multi-shot continuations or equivalent to them, while Julia and Python are a bit more limited. I am not familiar with many languages, so I'm sure I've missed a lot of instances of this sort of feature.

I would love to use LISP, but the libraries simply aren't there. Last time I tried Racket, there wasn't even a library for JSON.

I can't really speak to this because I haven't spent time trying to build real software using lisp.
