Deep cloning objects in JavaScript, the modern way
- austinjp 4y agoNice but still some caveats, from [0]: Prototypes. If you use structuredClone() with a class instance, you’ll get a plain object as the return value, as structured cloning discards the object’s prototype chain. Functions. If your object contains functions, they will be quietly discarded. Non-cloneables. Some values are not structured cloneable, most notably Error and DOM nodes. It will cause structuredClone() to throw. Web workers are patchy too. [0] https://web.dev/structured-clone/ https://web.dev/structured-clone/
