Go: Slice vs Array Use Cases

What are the main differences between slices and arrays in Go?

In Go, arrays have a fixed size, while slices are dynamic and can grow or shrink. Slices are more flexible.

When should I use a slice instead of an array?

Use slices when you need a resizable collection or when passing data to functions, as they are more efficient.

Can you give me an example of when to use an array?

Use arrays when you know the size of the collection won't change, like storing a fixed number of constants.

Are there performance differences between using slices and arrays?

Yes, slices can be more efficient for dynamic data, while arrays may have better performance for fixed-size data due to less overhead.
