I don't do Javascript, but any self-respecting language which calls itself safe is actually safe. I worked for decades in actually memory and type safe languages, and never ever heard of a memory or type safety bug.

Just not the cheaters: Rust, Java (until recently), and of course Javascript with its unsafe implementations.

Memory safety bug in a proper lisp? Unheard of, unless you break the GC or do wrong FFI calls.
