Deep Copy Js

Deep-copying in JavaScript

Shallow copy

Using the object spread operator … to shallow copy.

const objectA = {
  a: 1,
  b: 2,
};
const cloneA = { ...objectA };

Using JSON.stringify

const objectA = {
  a: 1,
  b: 2,
};
const deepCloneA = JSON.parse(JSON.stringify(objectA));

Using structuredClone. The global structuredClone() method creates a deep clone of a given value using the structured clone algorithm.

const objectA = {
  a: 1,
  b: 2,
};
const deepCloneA = structuredClone(objectA);
