AFAICT, the expectation is that the reader knows at least one modern programming language from the list, and maybe is acquainted in passing with a couple of others. So at least some comparisons should click.

(They seemingly don't use more apt comparisons with OCaml and Haskell, for instance, not expecting the reader to know them.)

Javascript I've seen a decent amount and tweaked/edited some of code in it but I wouldn't say I "know" it at all. Kotlin I've never even seen before and I know literally nothing about the language. Java I wrote a bit of in high school but haven't touched it in 15 years.

So yeah there's quite a lot that people wouldn't know.

Well, Golang? Pascal? They have similar ways of declaring data types, for instance.

This guide is not going to magically teach you Rust is there's nothing to compare it to; there are other guides to help those without a background. But it could somehow help people who already have similar concepts in their mind to link them to corresponding concepts in Rust.

Golang I've seen code of, but never worked with it. Pascal I've never seen before.

You've said what languages you don't know, what languages do you know?

C, C++, and Python are all languages I've worked professionally in. I'm in the process of learning Rust.
