The new StructuredCopy API solves this problem, and in this article, you’ll learn all the details about its usage.

> Nice, but seems like it's still consider quite new to be supported by browsers. Maybe we can ditch lodash's cloneDeep in the future.

> Was about time! I will keep using lodash for the time being, at least until we also get a native _.isEqual() and there's wide support in browsers. IMHO most (if not all) lodash methods should be provided natively, there's a reason why devs use them!

> Node.js 17 and above is now supported.

> I remember that there was an article about performance comparison of deep clone ways, and structuredClone was really slow.
