So at this fine grain of semantic detail, making strong statements about differing labels feels a little silly, but I have always thought that the difference is dynamic refers to typing, whereas scripting is usually a reference to the language being interpreted rather than compiled. Dynamically typed languages can certainly be compiled (I think Clojure qualifies here?).

And in that case, what do we make of QuickJS, which compiles JavaScript to bytecode?

What does this comment even mean? I can’t make heads or tails of it.
