What is the correct way to polyfill structuredClone?

[dragonlobster]

Hello, I am attempting to transpile code to ES5 and want to use structuredClone, however I'm in an runtime environment does not support it (goja). So I wish to polyfill this function, could someone point me in the right direction on how to achieve this. Thank you

You can try https://github.com/ungap/structured-clone.

We can find an indication by the MDN documentation at this link: https://developer.mozilla.org/en-US/docs/Web/API/structuredClone#see_also

As @JLHwung commented, you can try https://github.com/ungap/structured-clone but you also can try https://github.com/zloirock/core-js

IMHO https://github.com/zloirock/core-js looks like a better option because of the community behind it.

It's available from core-js@3.20, so it should be available, for example, in Babel with preset-env with proper settings.
