What are the best practices for using lodash merge?

When using lodash merge, it's important to understand how it handles deep merging and object references. Always ensure that the objects you're merging are structured correctly to avoid unexpected results.

Can you give me an example of deep merging with lodash?

Sure! If you have two objects like this: const obj1 = { a: { b: 1 } }; const obj2 = { a: { c: 2 } };, using _.merge(obj1, obj2) will result in { a: { b: 1, c: 2 } }.

What should I be cautious about when merging arrays?

When merging arrays, lodash will concatenate them by default. If you want to avoid duplicates, consider using _.uniq after merging.

Are there performance considerations I should keep in mind?

Yes, deep merging can be performance-intensive, especially with large objects. It's best to limit the depth of merging or use shallow merges when possible.
