How can I use Lodash to create a deep copy of an object?

You can use the _.cloneDeep() method from Lodash to create a deep copy of an object. This method recursively copies all properties.

Can you show me an example of how to use _.cloneDeep()?

Sure! Here's a simple example:

const _ = require('lodash');

const original = { a: 1, b: { c: 2 } };
const copy = _.cloneDeep(original);

console.log(copy); // { a: 1, b: { c: 2 } }

This creates a deep copy of the original object.

What happens if I modify the copy?

If you modify the copy, the original object remains unchanged. For example:

copy.b.c = 3;
console.log(original.b.c); // 2

This shows that the original object is unaffected.

Are there any limitations to using _.cloneDeep()?

Yes, _.cloneDeep() can have performance issues with very large objects or circular references. It's good to be aware of these when using it.
