How to Deep Copy a JavaScript Object with a Class?

Estimated read time 1 min read

One way to deep copy an object in JavaScript with a class is to use a combination of the Object.assign() method and the spread operator ... to create a new object with the properties and values of the original object.

Here’s an example:

class MyClass {
  constructor(value) {
    this.value = value;

const original = new MyClass(1);
const copy = Object.assign(new MyClass(), original, { value: original.value });

Alternatively, you can use JSON.parse(JSON.stringify(original)), but this method only works for objects with properties that can be represented as JSON data.
