Not really. Your first paragraph is also true for JS (think of ES6 "class" syntactic sugar). Some browsers implement the DOM in JavaScript (https://www.chromium.org/blink/blink-in-js, http://www.phantomjs.org/, https://github.com/andreasgal/dom.js). And there are things like asm.js and even Linux VM running in JavaScript (http://bellard.org/jslinux/). JavaScript/ECMAScript is one of the most misunderstood languages, please read up before jump at conclusions.
