Question about Array destructuring

Question

Can someone show me a good example of why we sometimes need to use a return array function instead of a normal Array for destructuring?

Answer 1

The reason is that the function can actually do something before it creates the array, for example it could retrieve those three values from a database.

Answer 2

What do you mean by "return array function"?
Can you show the code to explain?

Answer 3
