How can I use Lodash to merge two arrays?

How can I use Lodash to merge two arrays?

You can use the _.union method from Lodash to merge two arrays while removing duplicates. For example, _.union(array1, array2).

What if I want to keep duplicates?

If you want to keep duplicates, you can simply use the concat method: array1.concat(array2) will merge both arrays without removing any duplicates.

Can I merge more than two arrays at once?

Yes, you can merge multiple arrays using _.concat(array1, array2, array3, ...) or by using the spread operator: [].concat(...arrays).

Are there any performance considerations when merging large arrays?

Yes, performance can be affected by the size of the arrays and the method used. Using native methods like concat is generally faster than Lodash for simple merges.
