When should I use deep merge in programming?

When should I use deep merge in programming?

You should use deep merge when you need to combine nested objects without losing any data from either object.

Can you give me an example of deep merge in JavaScript?

Sure! In JavaScript, you can use libraries like Lodash's _.merge to deep merge two objects. For example: _.merge(obj1, obj2).

What are the performance implications of using deep merge?

Deep merging can be more resource-intensive than shallow merging, especially with large objects, so use it judiciously.

Are there any alternatives to deep merge?

Yes, alternatives include shallow merge or using libraries that provide immutability, like Immer, depending on your use case.
