function structuredClone

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.

Examples

Example 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

Parameters

value: any
