What is the difference between an array and a slice in Go?

  • An array has a fixed size, while a slice can grow dynamically.
  • An array can be multi-dimensional, while a slice is always 1-dimensional.
  • An array can store elements of different types.
  • A slice is a reference to an array.
The primary difference between an array and a slice in Go is that an array has a fixed size, which means it cannot change once it's defined, whereas a slice is a dynamic data structure that can grow or shrink as needed. Additionally, slices are more versatile because they are built on top of arrays and provide more flexibility when working with collections of data. Understanding this difference is crucial when deciding between arrays and slices for different use cases in Go.
