What is the difference between array merge and object merge in programming?

What is the difference between array merge and object merge in programming?

Array merge combines elements of two or more arrays, while object merge combines properties of two or more objects.

Can you give me an example of array merge?

Sure! In PHP, you can use array_merge() to combine arrays. For example: array_merge([1, 2], [3, 4]) results in [1, 2, 3, 4].

And how does object merge work?

In JavaScript, you can use Object.assign() to merge objects. For example: Object.assign({}, {a: 1}, {b: 2}) results in {a: 1, b: 2}.

Are there any performance differences between the two?

Yes, merging arrays can be faster than merging objects, especially with large datasets, due to the way they are stored in memory.
