JavaScript is backwards compatible going back effectively forever, as is Java. Rust's unique system is having a way to make breaking changes to the language without breaking old code, not that they prioritize supporting old code indefinitely.
The libraries are a different story—you're likely to have things break under you that rely on older versions of libraries when you update—but I don't see Rust actually having solved that.

Node and V8 are open source, which makes the code just as auditable and modifiable as the 3.6 million lines of Rust. Which is to say, both are equally unapproachable.

No language can fix that. However, I've lost count of the times my Python/JavaScript interpretation fails because of something in one of the dependencies. Usually, it's not a JS/Python problem but rather has to do with a Node/Python version update. It always boils down to the "core" issue which is the runtime. That's why I like that Rust give me a "fixed" runtime that I download/compile/package with my program.

I've recently patched a weird bug under Tokio/Otel and can't imagine doing that with Node/V8 without it being a major hassle. It is relatively straightforward in Rust though requires maintaining your own fork of only the dependency/branch in question.
