How can I use Lodash for cloning objects in JavaScript?

You can use the _.clone method from Lodash to create a shallow copy of an object. For deep cloning, use _.cloneDeep.

What's the difference between _.clone and _.cloneDeep?

_.clone creates a shallow copy, meaning nested objects are still referenced. _.cloneDeep creates a complete copy of the object, including nested objects.

Can you show me an example of using _.cloneDeep?

Sure! Here's an example:

const _ = require('lodash');
const original = { a: 1, b: { c: 2 } };
const deepClone = _.cloneDeep(original);
original.b.c = 3;
console.log(deepClone.b.c); // Outputs: 2

This shows that deepClone remains unaffected by changes to original.

Are there any performance considerations when using these methods?

Yes, _.cloneDeep can be slower than _.clone because it recursively copies all nested objects. Use it only when necessary.
