JavaScript can refer to the standard specification of ECMAScript, as well as the many implementations notably including v8 (chromium, node, deno), JavaScriptCore (webkit), and spidermonkey (Firefox), as well as some lesser known ones like duktape and QuickJS. And it can also be used to refer to an ECMAScript implementation plus an additional runtime platform like the Web API, or something like node or deno.

And Oracle doesn't control any of that. The only thing I know of that Oracle has related to JavaScript is Graal.js, which is just yet another implementation of ECMAScript, and didn't even exist for most of the time Sun and Oracle held the trademark.
