What are the performance differences between deep and shallow merging?

What are the performance differences between deep and shallow merging?

Deep merging involves recursively merging nested structures, while shallow merging combines top-level properties. Deep merging can be more computationally intensive due to its recursive nature.

In what scenarios would deep merging be preferred over shallow merging?

Deep merging is preferred when you need to preserve nested data structures, such as in complex state management in applications.

Are there any performance benchmarks comparing the two methods?

Yes, benchmarks typically show that shallow merging is faster for simple objects, while deep merging can be slower but necessary for complex data.

What libraries or tools can I use for deep and shallow merging?

Popular libraries include Lodash for JavaScript, which offers both deep and shallow merging functions, and deepmerge for deep merging.
