The builtin function append returns the updated slice after the append operation. This resulting slice is usually assigned back to the same variable that contained the original slice to which new values were appended.

Bad practice

x = []int{1, 3, 5}
append(x, 7) // returns the value []int{1, 3, 5, 7}. This is usually assigned back to x

x := []int{}
y := []int{}

x = append(y, 1) // possibly wrong

Recommended

x = []int{1, 3, 5}
x = append(x, 7)

x := []int{}
y := []int{}

y = append(y, 1) // append 1 to y
