> While [structuredClone()](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone) is presumably not related to any API (such as the DOM, file system or other), why is it not part of ECMAScript? Is there anything that prevents such a function from being defined as an ECMAScript standard? Are there any plans to add this or a similar function to the ECMAScript standard?
