Syntax: func Splice(elems *[]string, start, deleteCount int[, item ...string]) []string

The Splice() method changes the contents of an slice by removing or replacing existing elements and/or adding new elements in place.

Example-1

months := []string{"Jan", "March", "April", "June"}

deleteItem := gslice.Splice(&months, 1, 0, "Feb")

fmt.Println(months, deleteItem) // => [Jan Feb March April June] []

Example-2

months := []string{"Jan", "March", "April", "June"}

deleteItem := gslice.Splice(&months, 4, 1, "May")

fmt.Println(months, deleteItem) // => [Jan March April June May] []

Example-3

myFish := []string{"angel", "clown", "drum", "mandarin", "sturgeon"}

deleteItem := gslice.Splice(&myFish, 3, 1)

fmt.Println(myFish, deleteItem) // => [angel clown drum sturgeon] [mandarin]
