Appending Item to Slice in Go

We can add elements to the end of a slice using the built-in append() function.

append() takes the slice and one or more new values, and returns a new slice with those values added to the end:

arr1 := []int{1, 2, 3}
arr1 = append(arr1, 4)

// arr1 is now {1, 2, 3, 4}
