Deep Copying objects using JSON stringify and parse

Serialize and De-serialize

ref – https://dev.to/nas5w/js-fundamentals-object-assignment-vs-primitive-assignment-5h64

One method that can be used to deep copy an object is to serialize and de-serialize the object. One common way to do this is using JSON.stringify and JSON.parse.

const a = {

name: 'Joe',

dog: {

name: 'Daffodil',

};

const b = JSON.parse(JSON.stringify(a));

b.name = 'Eva';

b.dog.name = 'Jojo';

console.log(a);

// {

// name: 'Joe',

// dog: {

// name: 'Daffodil',

// },

// }

console.log(b);

// {

// name: 'Eva',

// dog: {

// name: 'Jojo',

// },

// }

However, it does not work on function objects:
