What is the difference between lodash's merge and assign?

Can you explain the difference between lodash's merge and assign methods?

Sure! _.assign copies properties from source objects to the destination object, while _.merge recursively merges properties.

What happens if there are nested objects in the source?

With _.assign, nested objects are overwritten, but _.merge will combine them, preserving the structure.

Can you give me an example of each?

Of course! For _.assign, if you have { a: { b: 1 } } and assign { a: { c: 2 } }, you'll get { a: { c: 2 } }. For _.merge, you'll get { a: { b: 1, c: 2 } }.

Which one should I use for deep cloning?

Use _.merge for deep cloning as it combines nested objects, while _.assign is better for shallow copying.
