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.

Example 1
const object = { x: 0, y: 1 };
const deepCopy = structuredClone(object);
deepCopy.x = 1;
console.log(deepCopy.x, object.x); // 1 0
const shallowCopy = object;
shallowCopy.x = 1;
// shallowCopy.x is pointing to the same location in memory as object.x
console.log(shallowCopy.x, object.x); // 1 1
