How can I create a deep copy of an object in JavaScript?

In JavaScript, you can create a deep copy of an object using methods like JSON.parse and JSON.stringify, or by using libraries like Lodash.

Can you show me an example using JSON methods?

Sure! Here's an example:

const original = { a: 1, b: { c: 2 } };
const deepCopy = JSON.parse(JSON.stringify(original));

This will create a deep copy of the original object.

What are the limitations of using JSON methods for deep copying?

The JSON methods won't copy functions, undefined values, or symbols. They also can't handle circular references.

Is there a better way to deep copy objects that include functions?

Yes, you can use libraries like Lodash with its _.cloneDeep() method, which can handle more complex objects.
