Modern ECMAScript implementations are a superset of the JavaScript language. Look, taking your spoken language analogy, things like the Deno KV store are an implementation of instructions doing something specific. In spoken/written language this could be a cooking receipt. Of course the receipt is not a language in itself, expect cooking is your language, haha, but it is written _in_ a language. You would never title a cook book a language.
