What operations exist on slices in Go?

In Go, slices are dynamic arrays that support the following operations:

1. Creating a slice:

   s := []int{1, 2, 3}
   s2 := make([]int, 5) // slice of length 5
   

2. Accessing elements:

   x := s[0] // first element
   s[1] = 10 // assignment
   

3. Changing length with append:

   s = append(s, 4, 5)
   

4. Slicing a slice:

   sub := s[1:3] // elements with indices 1 and 2
   

5. Copying slices:

   dst := make([]int, len(s))
   copy(dst, s)
   

6. Removing an element:

   // remove element at index i
   s = append(s[:i], s[i+1:]...)
   

7. Iterating:

   for i, v := range s {
       fmt.Println(i, v)
   }
   

8. Getting length and capacity:

   length := len(s)
   capacity := cap(s)
   

Thus, the main operations on slices include creation, access, resizing with append, slicing, copying, removing elements, and obtaining metadata (length, capacity).
