How do I use lodash's cloneDeep function?

The cloneDeep function in lodash is used to create a deep copy of an object. This means that it will recursively copy all properties, including nested objects.

Can you show me an example of how to use it?

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 } }

In this example, copy is a deep clone of original.

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 by changes to the copy.

Are there any performance considerations I should be aware of?

Yes, deep cloning can be more performance-intensive than shallow cloning, especially for large objects. It's important to consider the size and complexity of the object you're cloning.
