What is the difference between deep merge and shallow merge?
A shallow merge combines objects at the first level, while a deep merge combines all levels recursively.
Can you give me an example of a shallow merge?
Sure! If you have two objects, {a: 1, b: {c: 2}} and {b: {d: 3}}, a shallow merge would result in {a: 1, b: {d: 3}}.
And what about a deep merge?
In a deep merge, the result would be {a: 1, b: {c: 2, d: 3}} because it combines all nested properties.
When should I use deep merge over shallow merge?
Use deep merge when you need to combine nested objects, ensuring all properties are included.
