function structuredClone
structuredClone<T = any>(value: T,options?: StructuredSerializeOptions,): T
Creates a deep copy of a given value using the structured clone algorithm.
Unlike a shallow copy, a deep copy does not hold the same references as the source object, meaning its properties can be changed without affecting the source. For more details, see MDN.
Throws a DataCloneError
if any part of the input value is not
serializable.
