Miks on Go keeles soovitatav kasutada lõigu põhjal loodud massiivi?

In Go, it is recommended to use an array based on a slice, because slices are a more flexible and convenient data structure than arrays. Slices allow for dynamic resizing, while arrays have a fixed length.

By creating an array based on a slice, you can obtain a base array that will be used for storing data, and slices for easy access and management of this data. This helps to manage memory efficiently and avoid unnecessary copying.

Example:

// Create a slice with length 5
slice := make([]int, 5)

// underlyingArray — this is an array on which the slice is based
underlyingArray := slice[:]

// You can work with underlyingArray as a fixed-length array

Thus, the array serves as a base, and the slice as a convenient interface for working with data.
