IMHO this does not follow, for a few reasons:

- An experienced programmer would know that IEEE FP hardware is ubiquitous. Why would a language eschew that hardware capability by default? If anything, I would assume that any unfamiliar general-purpose language DOES start from that point (using IEEE float to represent non-integer numbers) because of historical precedent.

- "Number" is about as vague as you can get for a type name. Maybe personal bias here, but I find that vagueness invites research up front. "Time to read the documentation."

(I still expect a language newbie to get various bugs in new Javascript code, because the footguns in that language differ from the footguns in something like C++.)

Should we really optimize for someone writing in a new language without reading anything about it? Like, if he/she doesn’t even know that js numbers are floats, just don’t even let them close to a program.

No we should not, nor am I advocating for that.
